KVM: arm64: Move GICv5 timer PPI validation into timer_irqs_are_valid()

Browse source

Userspace can set the timer PPI numbers way before a GIC has been
created, leading to odd behaviours on GICv5 as we'd accept non
architectural PPI numbers.

Move the v5 check into timer_irqs_are_valid(), which aligns the
behaviour with the pre-v5 GICs, and is also guaranteed to run
only once a GIC has been configured.
