[PATCH 4/6] arm64: use hw_pte_t for fixmap HW PTEs

[Muhammad Usama Anjum]

fixmap_pte() returns a pointer into bm_pte, and early_fixmap_init_pte()
installs those arrays as page tables. Their elements are therefore
HW PTEs.

Change the element type of bm_pte to hw_pte_t so it matches the HW PTE
pointers returned and passed to the accessors. This is needed before
ARCH_HAS_HW_PTE_T makes HW PTEs and SW PTE values distinct types; the
array dimensions and placement are unchanged.
