Punit Agrawal 86d1c55ea6 KVM: arm64: Support PUD hugepage in stage2_is_exec() 
In preparation for creating PUD hugepages at stage 2, add support for
detecting execute permissions on PUD page table entries. Faults due to
lack of execute permissions on page table entries is used to perform
i-cache invalidation on first execute.

Provide trivial implementations of arm32 helpers to allow sharing of
code.
