mb/google/brya0: Enable CNVi DDR RFIM for brya0 variant
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 brya0 variant.
Refer to Intel doc:640438 and doc:690608 for more details.
BUG=b:201724512
BRANCH=None
TEST=Build and boot with debug FSP and verify CnviDdrRfim UPD value.
