KVM: arm64: Add nPIR{E0}_EL1 to HFG traps
nPIR_EL1 and nPIREO_EL1 are part of the 'reverse polarity' set of bits, set
them so that we disable the traps for a guest. Unfortunately, these bits
are not yet described in the ARM ARM, but only live in the XML description.
Also add them to the NV FGT forwarding infrastructure.
