mb/google/brya/variants/craask: Enable DDR RFIM Policy for Craask
DDR interfaces emit electromagnetic radiation which can couple
to the antennas of various radios that are integrated in the system,
and cause radio frequency interference (RFI). The DDR Radio Frequency
Interference Mitigation (DDR RFIM) feature is primarily aimed at
resolving narrowband RFI from DDR4/5 and LPDDR4/5 technologies
for the Wi-Fi high and ultra-high bands (~5-7 GHz).
This patch sets CnviDdrRfim UPD and enables CNVI DDR RFIM feature
for Craask variant.
Refer to Intel doc:640438 and doc:690608 for more details.
BUG=None
BRANCH=None
TEST=Build and boot Craask.
- Verified that Wifi DDR RFIM Feature is enabled and DDR RFI table can be modified.
