During the channel scanning process, the driver will continuously
switch channels. It seems that the full RF calibration step in
rt2800_config_channel() caused the channel scanning function to
timeout. To fix it, move the RF calibration to rt2800_enable_radio()
so that it is only executed once. This commit also includes some
coding format adjustments to follow the Linux recommended style.

This patch makes some improvements to the MT7620 RF calibration.
1. Move MT7620 PA/LNA calibration code to dedicated functions.
2. Restore RF and BBP registers before R-Calibration.
3. Do Rx DCOC calibration again before RXIQ calibration.
4. Use SoC specific AGC initial LNA value.
5. Correct MAC_RX_EN mask in rt2800_r_calibration()[1].

ath10k does not report excessive loss in case of broken block-ack

Currently, during initialization ath11k will receive a regulatory event
from the firmware in which it will receive the default regulatory domain
code and accompanying rules list and report those to the kernel.
Then if you try to change the regulatory domain to a different country code
it will do a weird thing in which it will send that to the FW and after
receiving the appropriate regulatory event it will parse the rules.
However, while its parsing there is a weird thing being done, and that is
that new raw rules from FW get intersected with the rules from the default
domain.
This is creating a big issue as the default domain is almost always set to
"US" or just "00" aka world so ath11k will unfairly limit you to the most
restrictive combination of rules based on the default domain and your
desired domain.
For example, in ETSI countries this is causing channels 12 and 13 on 2.4GHz
to not be usable since "US" limits 2.4GHz to 2472MHz instead of 2482MHz
like ETSI countries do.
So, lets do what TIP and even QCA do in their ath11k downstream tree and
completely get rid of the interesection code in ath11k.

ath11k is the upstream driver for Qualcomm 802.11ax radios, both for the
internal AHB and PCI based cards.
This commit does however only provide PCI support while AHB will follow
but its SoC specific so it will require an OpenWrt target first.
It differs a bit from ath10k as it requires stuff like QRTR, MHI and QMI
helpers.
PCI variant requires qrtr-mhi and mhi-bus which backports do provide,
however we are dropping those in a patch as they will conflict with
support for the AHB variant as that one requires qrtr-smd which in turn
requires RPMSG and GLINK and its not feasable to provide those in
backports as they are really SoC specific.
QRTR and MHI in kernel 5.10 are not usable and backporting the changes
is not easy as they have changed drastically from 5.10 to 5.15 ath11k will
only be available on targets that use kernel 5.15.

b) eLNA is driven the same way as ePA with mt7620's pin PA

Some ath10k IPQ40xx devices like the MikroTik hAP ac2 and ac3 require the
BDF-s to be extracted from the device storage instead of shipping packaged
API 2 BDF-s.
This is required as MikroTik has started shipping boards that require BDF-s
to be updated, as otherwise their WLAN performance really suffers.
This is however impossible as the devices that require this are release under
the same revision and its not possible to differentiate them from devices
using the older BDF-s.
In OpenWrt we are extracting the calibration data during runtime and we are
able to extract the BDF-s in the same manner, however we cannot package the
BDF-s to API 2 format on the fly and can only use API 1 to provide BDF-s on
the fly.
This is an issue as the ath10k driver explicitly looks only for the board.bin
file and not for something like board-bus-device.bin like it does for pre-cal
data.
Due to this we have no way of providing correct BDF-s on the fly, so lets
extend the ath10k driver to first look for BDF-s in the board-bus-device.bin
format, for example: board-ahb-a800000.wifi.bin
If that fails, look for the default board file name as defined previously.
So, backport the upstream ath10k patch.
