This adds support for UNII9 which requires to add a subband.
Just increase the number of subbands that we need to read.
Replace the usage of the IWL_NUM_SUB_BANDS_VX macros in acpi.h since
those macros are defined in the firmware API and ACPI declarations have
nothing to do the firmware API.

The structure in firmware runtime will need to grow because we're adding
a subband for UNII-9.
This means that we will soon no longer be able to just memcpy the data
from the UEFI table. The layout of the array will change.
Tediously copy the data byte-byte to make sure things get to the right
place even when we'll increase the number of subbands.
Make it easier for the uefi_cnv_var_ppag structure to grow by
simpiflying the layout it becomes an array of s8.
The layout of the structure becomes less obvious from the structure's
declaration, but then the code is more flexible.
Don't use UEFI_SAR_MAX_SUB_BANDS_NUM for the number of bands for PPAG.
Of course, SAR related structures will grow in future patches, but
decouple SAR and PPAG to make the work easier.

The APIs in uefi.h are not firmware API files nor are they pure software
objects. They really reflect a specific layout we expect to see in the
UEFI tables.
Since the UEFI objects are encoded into the BIOS, we can't use the same

object like iwl_sar_profile in the firmware runtime object.

When we fill the SAR values, we read values from the BIOS store in the
firmware runtime object and write them into the command that we send to
the firmware.
We assumed that the size of the firmware command is not longer than the
BIOS tables. This has been true until now, but this is not really safe.
We will soon have an firmware API change that will increase the size of
the table in the command and we want to make sure that we don't have a
buffer overrun when we read the firmware runtime object.

This patch continues the effort to refactor workqueue APIs, which has begun
with the changes introducing new workqueues and a new alloc_workqueue flag:
commit 128ea9f6cc ("workqueue: Add system_percpu_wq and system_dfl_wq")
commit 930c2ea566 ("workqueue: Add new WQ_PERCPU flag")
The point of the refactoring is to eventually alter the default behavior of
workqueues to become unbound by default so that their workload placement is
optimized by the scheduler.
Before that to happen after a careful review and conversion of each individual
case, workqueue users must be converted to the better named new workqueues with
no intended behaviour changes:
system_wq -> system_percpu_wq
system_unbound_wq -> system_dfl_wq

Drop the mt792x_sta_to_link() lookup in mt7925_mcu_bss_basic_tlv() and
pass the resolved WCID indices from the caller instead. The link
context is already known, so the lookup is redundant.
This makes link ownership explicit and keeps the helper lookup-free.
No functional change intended.

Drop the mt792x_sta_to_link() lookup in mt7925_mcu_sta_amsdu_tlv() and
pass mlink from the caller instead. The link context is already known
so the lookup is redundant.
This makes link ownership explicit and keeps the helper lookup-free.
No functional change intended.

Disallow triggering radar detection on non-DFS channels to prevent paused
TX queues from failing to resume, as a channel switch is not performed in
this case.

Align the vendor driver by adjusting the timeout values for the
MCU_UNI_CMD_EFUSE_CTRL and MCU_UNI_CMD_EXT_EEPROM_CTRL commands.
Without this adjustment, false positive command timeout errors may occur,
especially on some iPA variants.

Skip WFSYS reset during bootup for MT7990 chipsets; only reset if L0.5
recovery is triggered.
Without this fix, the following kernel error may occur:
Internal error: synchronous external abort.

For MT7990 chipsets, critical packet mode must be enabled. Without this,
some higher priority packets may be placed in the wrong AC queue.

overwriting the entire register.

mt7925u uses different reset/status registers from mt7921u. Reusing the
mt7921u register set causes the WFSYS reset to fail.
Add a chip-specific descriptor in mt792xu_wfsys_reset() to select the
correct registers and fix mt7925u failing to initialize after a warm
reboot.
