KVM: arm64: Handle PIR{,E0}_EL2 traps

Browse source

Add the FEAT_S1PIE EL2 registers the sysreg descriptor array so that
they can be handled as a trap.

Access to these registers is conditional based on ID_AA64MMFR3_EL1.S1PIE
being advertised.

Similarly to other other changes, PIRE0_EL2 is guaranteed to trap
thanks to the D22677 update to the architecture.
