arm64/mm: Use phys_to_page() to access pgtable memory
The macros {pgd, pud, pmd}_page() retrieves the page struct of the
corresponding page frame, which is reserved as page table. There
is already a macro (phys_to_page), defined in memory.h as below,
to convert the physical address to the page struct. Also, the header
file (memory.h) has been included by pgtable.h.
#define phys_to_page(phys) (pfn_to_page(__phys_to_pfn(phys)))
So it's reasonable to use the macro in pgtable.h.
