arm64: Move the content of bpi.S to hyp-entry.S

Browse source 
bpi.S was introduced as we were starting to build the Spectre v2
mitigation framework, and it was rather unclear that it would
become strictly KVM specific.

Now that the picture is a lot clearer, let's move the content
of that file to hyp-entry.S, where it actually belong.
