[RFC PATCH v2 16/19] KVM: arm/arm64: Move phys_timer_emulate function

[Christoffer Dall <cdall@linaro.org>]

We are about to call phys_timer_emulate() from kvm_timer_update_state()
and modify phys_timer_emulate() at the same time.  Moving the function
and modifying it in a single patch makes the diff hard to read, so do
this separately first.

No functional change.
