soc/intel/meteorlake: Provide mitigation support for CNVi RFI

the Intel integrated Wi-Fi firmware(CNVi) for Meteor Lake. Please refer

commit hash 6f73a20 (soc/intel/alderlake: Move CnviDdrRfim property to
drivers) and provides the CNVi RFIM support for Meteor Lake.

TEST=Booted to OS on Rex. Looked the DDR_DVFS_RFI_CONFIG_PCU_REG
register at the offset 0x5A40 of Mchbar and verified the BIT0
(RFI_DISABLE bit) is 0.
