The first patch fixes a bug due to incorrect DIRECTMAP_SIZE calculation.
The second patch removes unused macro FRAMETABLE_VIRT_END.
The third patch hardens the setup_frametable_mappings by adding a sanity check
for the size of struct page_info and calling panic if the calculate size of
the frametable exceeds the limit.
Sent together for ease of merging.

xen/arm64: Fix incorrect DIRECTMAP_SIZE calculation

xen/arm: Harden setup_frametable_mappings
