ARM64 standard pgtable functions are going to use pgtable_page_[ctor|dtor]
constructs. Certain stage-2 page table allocations are multi order which
cannot be allocated through a generic pgtable function as it does not exist
right now. This prevents all pgtable allocations including multi order ones
in stage-2 from moving into new ARM64 (pgtable_page_[ctor|dtor]) pgtable
functions. Hence remove all generic pgtable allocation function dependency
from stage-2 page tables till there is one multi-order allocation function
