Currently phys_to_virt() does not work well on 52-bits VA arm64 kernel.
One issue is contributed by phys_offset not signed.
The other is contributed by wrong page_offset.
v1 -> v2
Fix broken patch [2/3] in v1
Move arch_scan_vmcoreinfo declaration to util_lib/include/elf_info.h
Using UINT64_MAX instread of 0xffffffffffffffff

arm64/crashdump: unify routine to get page_offset
arm64: read VA_BITS from kcore for 52-bits VA kernel
