skylake/devicetree: Add PIRQ Routing programming
Program PIRQ Routing with correct values, as done by FSP, and also in 'soc/intel/skylake/romstage/pch.c' file. If not done, these values get overridden by "0" during PxRC -> PIRQ programming in ramstage, in 'soc/intel/skylake/lpc.c' file pch_pirq_init()function.
