dpaa2-eth: add QBMAN statistics

This patch set adds ethtool statistics for pending frames/bytes

The first patch adds support for the query APIs in the DPIO driver

In case a command which completes in Command Status was sent using the
hci_cmd_send-family of APIs there would be a misleading error in the
hci_get_cmd_complete function, since the code would be trying to fetch
the Command Complete parameters when there are none.

Avoid the misleading error and silently bail out from the function in
case the received event is a command status.

The Broadcom controller on aries S5PV210 boards sends out a couple of
unknown packets after the firmware is loaded.  This will cause
logging of errors such as:
	Bluetooth: hci0: Frame reassembly failed (-84)

This is probably also the case with other boards, as there are related
Android userspace patches for custom ROMs such as
https://review.lineageos.org/#/c/LineageOS/android_system_bt/+/142721/
Since this appears to be intended behaviour, treated them as diagnostic
packets.

On many devices the RTL8723BS device gets reset during suspend/resume,
causing it to lose its firmware and all state.

Testing has shown it drops back to communicating at 115200 bps and sends
sync-request packages, indicating it has been fully reset.

This commit fixes this by queueing a reprobe on resume.

This mirrors how USB RTL BT devices, which have the same problem, are
handled in the btusb driver, there we set the USB_QUIRK_RESET_RESUME for
all RTL devices, which also causes a reprobe on resume. The only difference
is that here we need to do the reprobe ourselves.

Since we are doing a full reprobe on resume now, we can also turn off the
device on suspend to save power while suspended.

The datasheets for BCM20702 and BCM43438 both have power up time
sequence graphs, however they are slightly different. Both chips
also have an internal power-on-reset, which holds the chip in reset
for a short time after the regulators are enabled.

For the BCM20702, the time period from when the regulators are enabled,
until the chip settles and comes out of sleep state, is 6564 ~ 8171 us.

For the BCM43438, the graph only shows the time period from when the
regulators are enabled until the chip responds by driving the host's
CTS line low, assuming the host has already driven its RTS line low.
This is shown to be 6.5 sleep cycles, with the sleep clock at 32.768
kHz. This is around 2 ms.

Wait a full 10 ms after the regulators are enabled to account for signal
rising times.

Originally the device tree binding only specified one clock reference,
with the name "extclk". The driver simply retrieves the clock without
bothering to specify a name.

Since we added a second clock to the binding, we need to fetch the
clocks by name now. First we try the new name "txco", then fall back
to the old name "extclk", and finally try retrieving a clock without
using any name, to cover any instances where a bad device tree or
firmware worked by accident.

In the last case, we should take care that we don't get the same
clock twice when we add support for the "lpo" clock.

The driver currently checks the clk pointer for an error condition, as
returned by clk_get, before every invocation of the clk consumer API.
This is redundant if the goal is simply to ignore the errors, thereby
making the clk optional. The clk consumer API already checks if the
pointer is NULL or not.

Simplify the code a bit by assigning NULL to the clk pointer if the
error condition is one we want to ignore, which is every error except
deferred probing.

The Broadcom Bluetooth controllers can take up to two external clocks:
an external frequency reference, substituting the main crystal, and a
LPO clock at 32.768 kHz substituting the internal LPO clock.

In particular, the external LPO clock must be used when the controller
does not have NVRAM connected, and the main reference frequency is not
the default 20 MHz. This is described in detail in the datasheet.

The original "extclk" clock name is ambiguous as to which of these it
refers to, and some designs might even require both.

This patch deprecates the existing name, and adds "txco" and "lpo".
