Now that all the needed pieces are in place implement suspend support QCA6390
PCI devices. All other devices will return -EOPNOTSUPP during suspend. The
suspend is implemented by switching the firmware to WoW mode during suspend, so
the firmware will be running on low power mode while host is in suspend.

At the moment we are not able to shutdown and fully power off the device due to
bugs in MHI subsystem, so WoW mode is a workaround for the time being.

During suspend we enable WoW mode, disable CE irq and DP irq, then put MHI to
suspend state.  During resume, driver resumes MHI firstly, then enables CE irq
and dp IRQ, and sends WoW wakeup command to firmware.

The driver_data area of ieee80211_tx_info is used in ath11k for
ath11k_skb_cb. The first function in the TX patch which rewrites it to
ath11k_skb_cb is already ath11k_mac_op_tx. No one else in the code path
must use it for something else before it reinitializes it. Otherwise the
data has to be considered uninitialized or corrupt.

But the ieee80211_tx_info.control shares exactly the same area as
ieee80211_tx_info.driver_data and ath11k is still using it. This results in
best case in a

  ath11k c000000.wifi1: no vif found for mgmt frame, flags 0x0

or (slightly worse) in a kernel oops.

Instead, the interesting data must be moved first into the ath11k_skb_cb
and ieee80211_tx_info.control must then not be used anymore.

Current ring selector logic follows round-robin scheduling,
when a process switch from one processor to another each time,
the data in the cache would have to be invalidated
and re-loaded from RAM leads to poor cache utilization.

Therefore smp_processor_id() attempt to keep processes
on the same processor via processor affinity which improves
cache utilization. Also, ring selection could be chosen round
robin when the processor_id based ring selection does not
have the resources.

cold boot calibration is the process to calibrate all the channels
during the boot-up to avoid the calibration delay during the
channel change.
During the boot-up, firmware started in cold boot calibration mode
Firmware calibrate all channels and generate CalDb(DDR).
Subsequent wifi bringup will reuse the same CalDb.
Firmware is restarted in normal mode to continue the normal operation.

caldb memory address send to firmware through the QMI message.Firmware
use this address to store the caldb data and use it until next reboot.

This will give the improvement during the channel change. But it is
increasing the boot-up time(up to 15sec depend on number of radios).
So if the user want to reduce the boot-up time and accepting for channel
change delay, user can disable this feature using the module param
cold_boot_cal=0.

Board Data File (BDF) is loaded upon driver boot-up procedure. The right
board data file is identified on IPQ6018 using bus, qmi-chip-id and
qmi-board-id.

The problem, however, can occur when the (default) board data file cannot
fulfill with the vendor requirements and it is necessary to use a different
board data file.

This problem was already solved on ath10k by adding a ",variant=.*" at the
end of the board name. The same functionality must also be provided for
ath11k.

The device tree requires an additional string to define the variant name

    wifi@c000000 {
        status = "okay";
        qcom,ath11k-calibration-variant = "Cigtech-WF-188";
    };

This would create the boarddata identifier for the board-2.bin search

 *  bus=ahb,qmi-chip-id=0,qmi-board-id=18,variant=Cigtech-WF-188

The mon status ring doesn't support interrupt so far, so host starts
a timer to reap this ring. The timer handler also reaps the
rxdma_err_dst_ring in case of monitor mode.

As QCA6390 requires bss created ahead of starting vdev, so check
vdev_start_delay for monitor mode.

For QCA6390, it uses wbm_desc_rel_ring to return descriptors.
It also uses rx_refill_buf_ring to fill mon buffer instead of
rxdma_mon_buf_ring.

For QCA6390, only one pdev is created and this pdev manages both lmacs, thus
both rxdmas. So host needs to initialize all rxdma related rings for one pdev.

Another difference is for QCA6390, host fills rxbuf to firmware and firmware
further fills the rxbuf to rxbuf ring for each rxdma.

PCI devices like QCA6390 load the board file differently, add support for that
and the method is chosen using bus_params variables.

Add support to create board name for different targets.  This board name is
used to parse the board data from board-2.bin for ahb/pci based targets.

As struct target_mem_chunk::vaddr was changed from 'u32' to 'u32 *' in
ath11k_qmi_assign_target_mem_chunk() vaddr assignments were changed to NULL to
avoid a compilation warning. IPQ8074 does not use the vaddr field for anything
so that change does not affect functionality.

At the moment this only supports board files with BIN type. Support for ELF
type, which seems to be more popular on QCA6390 devices, needs to be added later.

Add direct buffer ring (dbring) with helper API, which is used by the
spectral scan. Initialise the direct buffer ring based on the dma ring
capability, which get announced in the wmi service ready extended event.
This ring is slightly changed from data path rings. Compare to data path
ring this ring shares the hp and tp address to firmware though WMI commands.
Also the replenish buffer size is derived from firmware announcement.
driver receive indication through WMI event
WMI_PDEV_DMA_RING_BUF_RELEASE_EVENTID.
