wifi: iwlwifi: support BIOS override for 5G9 in CA also in LARI version 8
Commit 6b3e87cc0ca5 ("iwlwifi: Add support for LARI_CONFIG_CHANGE_CMD
cmd v9")
added a few bits to iwl_lari_config_change_cmd::oem_unii4_allow_bitmap
if the FW has LARI version >= 9.
But we also need to send those bits for version 8 if the FW is capable
of this feature (indicated with capability bits)
Add the FW capability bit, and set the additional bits in the cmd when
the version is 8 and the FW capability bit is set.
