mb/google/brya/variants/*: Add cpu pcie rp flags
Along with commit f94405219c (soc/intel/alderlake: Hook up FSP-S CPU
PCIe UPDs), we need to set cpu pcie rp flags in devicetree now.
This CL is to add proper cpu pcie flags (PCIE_RP_LTR and PCIE_RP_AER) in
all intel projects or system will be blocked at PKGC2R with root port
LTR not enable.
BUG=b:214009181
TEST=Build and DUT (Kano) can enter deeper PKGC state normally.
