When enabled, add identifiers in ACPI tables that are common

help
Enable it when wifi driver uses SAR configuration feature.
VPD entry "wifi_sar" is read to get SAR settings, if its
not found driver may look into CBFS for default settigs.
WIFI_SAR_CBFS is option to enable CBFS lookup.

help
wifi driver would look for "wifi_sar" vpd key and load SAR settings from
it, if the vpd key is not found then the driver tries to look for sar
settings from CBFS with file name wifi_sar_defaults.hex.
So OEM/ODM can override wifi sar with VPD.

help
There can be up to 3 optional SAR table sets.
