KVM: arm64: Add REQUIRES_E2H1 constraint as configuration flags

Browse source

A bunch of EL2 configuration are very similar to their EL1 counterpart,
with the added constraint that HCR_EL2.E2H being 1.

For us, this means HCR_EL2.E2H being RES1, which is something we can
statically evaluate.

Add a REQUIRES_E2H1 constraint, which allows us to express conditions
in a much simpler way (without extra code). Existing occurrences are
converted, before we add a lot more.
