KVM: arm64: Disable hierarchical permissions when S1PIE is enabled
S1PIE implicitly disables hierarchical permissions, as specified in
R_JHSVW, by making TCR_ELx.HPDn RES1.
Add a predicate for S1PIE being enabled for a given translation regime,
and emulate this behaviour by forcing the hpd field to true if S1PIE
is enabled for that translation regime.
