Aarch64 kvm exit reason defination is out of date for some time, so in
this patch:
1. Sync some newly introduced or missing EC definations.
2. Change the WFI to WFx.
3. Fix the comment.

Not all the definations are used or usable for aarch64 kvm, but it's
better to keep align across the whole kernel.
