Ubuntu 21.10 (Impish Indri) has reached end of life, so this bug will
not be fixed for that specific release.

Bug description:
[SRU Justification]
[Impact]
After applied patches from bug 1933938 to enable AX201 on ADL platforms,
some of them may still fail to functioning stably due to fw error when
LARI_CONFIG_CHANGE command is sent. With CONFIG_IWLWIFI_DEBUG turned on,
following error appears:
iwlwifi 0000:00:14.3: iwl_mvm_lari_cfg sending LARI_CONFIG_CHANGE,
config_bitmap=0x8, oem_11ax_allow_bitmap=0xf
iwlwifi 0000:00:14.3: iwl_trans_txq_send_hcmd_sync Attempting to send
sync command UNKNOWN
iwlwifi 0000:00:14.3: iwl_trans_txq_send_hcmd_sync Setting HCMD_ACTIVE
for command UNKNOWN
Then begin FW error, hardware reset.
[Fix]
Commit 54b4fda5a761 ("iwlwifi: mvm: Read acpi dsm to get unii4
enable/disable bitmap") is required to fix this issue. The other commit
is pulled in for dependency.
[Test Case]
Install a prebuilt kernel with these fixes, put DUT under idle for 5
mins and check if there is still firmware error messages.
[Where problems could occur]
There is little chance that it can ever go wrong judging from the
simplexity of the two commits.
[Other Info]
While the two patches have already been included in mainline and
therefore Ubuntu unstable, only oem-5.13 and impish are nominated.
