coreboot needs to propagate the CnviDdrRfim value info of the feature
enable/disable state into the CNVi via the WiFi DSM ACPI object. This
will be consumed by the Wi-Fi driver and it will act according to
CB enablement configuration. This patch adds _DSM method for that.
Add support for following 2 functions in _DSM method
- Function 0: Function Support Query Returns a bitmask of functions
supported.
- Function 3: RFI enablement 0 Feature Enable 1 Feature Disable
Note: Wifi Dsm already has provision for SAR. This patch will add
additional support to return RFIM structure based on UUID.
