wifi: iwlwifi: interpret STEP URM BIOS configuration
For certain platforms, it may necessary to use the STEP in URM
(ultra reliable mode.) Read the necessary flags from the BIOS
(ACPI or UEFI) and indicate the chosen mode to the firmware in
the context info. Whether or not URM really was configured is
already read back later, to adjust capabilities accordingly.
