This change makes WIFI_SAR_CBFS user selectable option so that it can
be enabled/disabled from menuconfig along with the SAR filepath.

To comply with all relevant bodies throughout the world, SAR settings
take into account the lowest common denominator Tx power settings. This
setup may lead to non-optimal performance when the user location is in a
country that may allow higher power setting. The purpose of Wireless Geo
Delta Settings (WGDS) is to provide offset settings for FCC, Europe,
Japan and Rest of the world. These offsets would be added (by Intel wifi
driver) to the base SAR Tx Power as defined in WRDS and EWRD
BUG=b:65155728
BRANCH=none
TEST=WGDS ACPI table gets created as expected.

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.

When compiling a non-x86 platform with DRIVERS_INTEL_WIFI enabled,
we get the build error:
src/drivers/intel/wifi/wifi.c:17:30: fatal error:
arch/acpi_device.h: No such file or directory
acpi_device.h only exists in the x86 architecture directory.

Keep this enabled by default as most x86 platforms could have PCI-e
slots equipped with one of these Intel WiFi adapters.
The Kconfig entries under google boards had no function previously,
the variable was never referenced.
