drivers/wifi,soc/intel/adl: Move CnviDdrRfim property to drivers

Some non-SoC code might want to know whether or not the CNVi DDR RFIM
feature is enabled. Also note that future SoCs may also support this
feature. To make the CnviDdrRfim property generic, move it from
soc/intel/alderlake to drivers/wifi/generic instead.
