mb/google/rex: Use FW_CONFIG for generating ACPI code for WIFI
This patch avoids creating runtime ACPI for unused WIFI solutions.
For example: if the Rex SKU is with WIFI_CNVI then you don't need
to populate ACPI code for WIFI_PCIE.
FW_CONIG can be used for making those decisions.
TEST=No ASL entries being created for WIFI_PCIE if the FW_CONIG is
set to WIFI_CNVI.
Also, helped to save the boot time on google/rex (FSP-S API) by 9ms.
