2024-02-02wifi: iwlwifi: separate TAS 'read-from-BIOS' and 'send-to-FW' flowsMiri Korenblit5-37/+31
Currently the TAS 'read-from-BIOS' flow receives the command struct and the version of it as read from FW TLVs, and fills the command accordingly. This seems wrong, we should have the 'read-from-BIOS' flow (iwl_acpi_get_tas in iwlwifi) reading/parsing/validating the table from BIOS, and the 'send-to-FW' flow (iwl_mvm_tas_init) doing all the FW versioning checks and cmd filling.

There is a requirement from OEMs to support a new bit in DSM function 8, which will indicate that this device is an indoor one, and that it should activate UNII-1 (5.2GHz) sub band in the World Wide Geo Profile.

In reality 64 bytes are enough to hold fw version string, but some compilers can complain (with W=1) that output may be truncated when building this string with snprintf. Increase the size to avoid this sort of warnings and state explicitely that we want the size to be trancated to 32 bytes.
