intel/wifi: Create ACPI objects for wifi SAR configuration
To support intel wifi SAR configuration, it is required coreboot
to publish two ACPI objects (WRDS and EWRD) to supply SAR limit
data sets. VPD entry "wifi_sar" is required to supply the raw SAR
limit data.
BUG=chrome-os-partner:60821
TEST=Enable USE_SAR, boot reef to OS, create the VPD entry, reboot,
check the SSDT dump and verify WRDS and EWRD structures.
