wifi: mt76: mt7921e: stop chip reset worker in unregister hook
If the chip reset worker is triggered during the remove process, the chip
DMA may not be properly pushed back to the idle state. This can lead to
corruption of the DMA flow due to the chip reset. Therefore, it is
necessary to stop the chip reset before the DMA is finalized.
To avoid resetting the chip after the reset worker is cancelled, use
__mt7921_mcu_drv_pmctrl() instead of mt7921_mcu_drv_pmctrl(). It is safe to
ignore the pm mutex because the pm worker and wake worker have already been

wifi: mt76: mt7921e: improve reliability of dma reset
The hardware team has advised the driver that it is necessary to first put
WFDMA into an idle state before resetting the WFDMA. Otherwise, the WFDMA
may enter an unknown state where it cannot be polled with the right state
successfully. To ensure that the DMA can work properly while a stressful
cold reboot test was being made, we have reordered the programming sequence
in the driver based on the hardware team's guidance.
The patch would modify the WFDMA disabling flow from
"DMA reset -> disabling DMASHDL -> disabling WFDMA -> polling and waiting
until DMA idle" to "disabling WFDMA -> polling and waiting for DMA idle ->
disabling DMASHDL -> DMA reset.
Where he polling and waiting until WFDMA is idle is coordinated with the
operation of disabling WFDMA. Even while WFDMA is being disabled, it can
still handle Tx/Rx requests. The additional polling allows sufficient time
for WFDMA to process the last T/Rx request. When the idle state of WFDMA is
reached, it is a reliable indication that DMASHDL is also idle to ensure it
is safe to disable it and perform the DMA reset.

mt76: mt7921: fix kernel panic by accessing unallocated eeprom.data

been removed completely since
commit
16d98b548365 ("mt76: mt7921: rely on mcu_get_nic_capability").
This could result in potential invalid memory access.
To fix the kernel panic issue in mt7921, it is necessary to avoid accessing
unallocated eeprom.data which can lead to invalid memory access.
Furthermore, it is possible to entirely eliminate the
mt7921_mcu_parse_eeprom function and solely depend on
mt7921_mcu_parse_response to divide the RxD header.

One chip can have different RFE (RF front end) types which we will judge
at runtime. And, different RFE types may use different RF parameter tables.
Though we didn't really meet this case previously, we are going to meet it
on upcoming chip RTL8851B. So, this commit handles parameter tables for
runtime RFE type.
We now encapsulate rtw89_txpwr_rule_<2/5/6>ghz tables into rtw89_rfe_parms.
Then, each chip defines its default parameter tables, and if needed, it can
configure extra parameter tables by RFE type. Finally we determine runtime
parameter tables by RFE type if one is configured. Otherwise, we use the
default parameter tables.
For now, we just move all settings under default parameter tables. We will
