[PULL,09/13] KVM: arm: rename pm_fake handler to trap_raz_wi

Commit Message

From: Zhichao Huang <[e-mail]>

pm_fake doesn't quite describe what the handler does (ignoring writes
and returning 0 for reads).

As we're about to use it (a lot) in a different context, rename it
with a (admitedly cryptic) name that make sense for all users.
