wifi: iwlwifi: Add support for LARI_CONFIG_CHANGE_CMD cmd v9

Browse Source 
There is a requirement from OEMs to support new bits in DSM function 7,
which will indicate enablement of 5.9 GHz in Canada.
Add support for this by reading those bits from BIOS and sending it to the
FW. mask unii4 allow bitmap based on LARI_CONFIG_CHANGE_CMD version
