mb/google/brya/variants/nivviks: Enable DDR RFIM Policy for Nivviks
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 Nivviks variant.
Refer to Intel doc:640438 and doc:690608 for more details.
BUG=b:237238786
BRANCH=None
TEST=Build and boot Nivviks.
- Verified that Wifi DDR RFIM Feature is enabled and DDR RFI table can be modified.
