kvm_hwpoison_page_add() and kvm_unpoison_all() will be used both
by X86 and ARM platforms, so move these functions to a common
accel/kvm/ folder to avoid duplicate code.

it's not file for KVM specific code,
maybe Paolo could suggest a bettor place ...

I remember some people suggests me to move the code to KVM before, may be he is Peter.
