KVM: arm64: nv: Use literal granule size in TLBI range calculation

Browse source

TLBI handling derives the invalidation range from guest VTCR_EL2.TG0 in
get_guest_mapping_ttl() and compute_tlb_inval_range(). Switch these to
use a helper that returns the decoded VTCR_EL2.TG0 granule size instead
of decoding it inline.

This keeps the granule size derivation in one place and prepares for
following changes that adjust the effective granule size.
