arm64: Fix 5-level paging support in kexec/hibernate trampoline
Add the missing code to allocate P4D level page tables when cloning the
the kernel page tables. This fixes a crash that may be observed when
attempting to resume from hibernation on an LPA2 capable system with 4k
pages, which therefore uses 5 levels of paging.
Presumably, kexec is equally affected.
