The 9260-1x1 device can be differentiated using the PCI device ID.
There is a single occurrence of this device, so continue relying on
the device and subsystem device IDs.

The name of this device was incorrect, so add a new string
specifically for it.

TH1 devices can now be fully differentiated by using the device
parameters we have (particularly the RF_TYPE).  Start using these
parameters instead of hardcoding to specific subsystem device IDs.

This also fixes the name of one of the TH1 devices that was
erroneously using the 9260 struct and renames 9160 to 9162.

Pu, PnJ and Th devices have different combinations of PCI ID, MAC ID
and RF IDs.  Use these to differentiate them and choose the correct
configuration.

This also includes a change from using soc cfg's for 0x2526
devices (PnJ/Th), which was incorrect.

Devices that also include a GNSS module have different names, so add a
new device option to differentiate them, according to the values we
have in the modules section of the subsystem device ID.

Additionally, convert the two applicable devices to use this value

Add MAC ID, RF ID and the bit that tells us whether the device can

In a recent change to the SPI subsystem [1], a new `delay` struct was added
to replace the `delay_usecs`. This change replaces the current
`delay_usecs` with `delay` for this driver.

The `spi_transfer_delay_exec()` function [in the SPI framework] makes sure
that both `delay_usecs` & `delay` are used (in this order to preserve
backwards compatibility).

hard_header_len provides limitations for things like AF_PACKET, such
that we don't allow transmitting packets smaller than this.

needed_headroom provides a suggested minimum headroom for SKBs, so that
we can trivally add our headers to the front.

The latter is the correct field to use in this case, while the former
mostly just prevents sending small AF_PACKET frames.

In any case, mwifiex already does its own bounce buffering [1] if we
don't have enough headroom, so hints (not hard limits) are all that are
needed.

This is the essentially the same bug (and fix) that brcmfmac had, fixed
in commit cb39288f ("brcmfmac: use ndev->needed_headroom to reserve
additional header space").

Quantenna Pearl device exposes multiple (up to 3) radio interfaces under
single PCIe function. So far all the wiphy devices were attached to the
same pcie device. As a result, all different wireless network devices
were reported under the same sysfs directory for pcie device, e.g.:

$ ls  /sys/class/net/wlan0/device/net/
  wlan0 wlan1

It turns out that such behavior may confuse various users of wireless
subsystem. For instance, it turned out to be the case for:
- Linux init systems, e.g. for renaming based on parent device
- OpenWRT configuration scripts

Suggested solution is to add an intermediate virtual platform device
for each radio interface.

The NCM specification defines two formats of transfer blocks: with 16-bit
fields (NTB-16) and with 32-bit fields (NTB-32). Currently only NTB-16 is
implemented.

This patch adds the support of NTB-32. The motivation behind this is that
some devices such as E5785 or E5885 from the current generation of Huawei
LTE routers do not support NTB-16. The previous generations of Huawei
devices are also use NTB-32 by default.

Also this patch enables NTB-32 by default for Huawei devices.

During the 2019 ValdikSS made five attempts to contact Huawei to add the
NTB-16 support to their router firmware, but they were unsuccessful.
