Since the hypervisor always uses 4K as its page size, the size of PFNs
used for gpadl should be HV_HYP_PAGE_SIZE rather than PAGE_SIZE, so
adjust this accordingly as the preparation for supporting 16K/64K page
size guests.

It may be worth calling out there is no change on x86 because
HV_HYP_PAGE_SHIFT and PAGE_SHIFT are of the same value there.

Sure, I will call it out in the commit log of the next version, thanks!
