Subject[PATCH v1 2/2] KVM: arm: rename pm_fake handler to trap_raz_wi
Date
From: Zhichao Huang <zhichao.huang@linaro.org>

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.
