KVM: arm64: Handle AArch32 SPSR_{irq,abt,und,fiq} as RAZ/WI

Browse source

When trapping accesses from a NV guest that tries to access
SPSR_{irq,abt,und,fiq}, make sure we handle them as RAZ/WI,
as if AArch32 wasn't implemented.

This involves a bit of repainting to make the visibility
handler more generic.
