All code in PPC KVM currently accesses gprs in the vcpu struct directly.
While there's nothing wrong with that wrt the current way gprs are stored
and loaded, it doesn't suffice for the PACA acceleration that will follow
in this patchset.
So let's just create little wrapper inline functions that we call whenever
a GPR needs to be read from or written to. The compiled code shouldn't really
change at all for now.

TLB entry should enable memory coherence in SMP.
And like commit 631fba9dd3aca519355322cef035730609e91593,
remove guard attribute to enable the prefetch of guest memory.

Should clear and then update the next victim area here.
Guest kernel only read TLB1 when startup kernel,
this bug result in an extra 4K TLB1 mapping in guest from 0x0 to 0x0.
As the problem has no impact to bootup a guest,
we didn't notice it before.
