KVM: arm64: Add S1 IPA to page table level walker

Browse source

Use the filtering hook infrastructure to implement a new walker
that, for a given VA and an IPA, returns the level of the first
occurence of this IPA in the walk from that VA.

This will be used to improve our SEA syndrome reporting.
