[PATCH v8 08/15] drm/i915: use hw_pte_t for PTE range callbacks

[Alexander Gordeev <agordeev@linux.ibm.com>]

From: Muhammad Usama Anjum <usama.anjum@arm.com>

apply_to_page_range() now passes PTE table storage to its callback as
hw_pte_t *. Update the i915 remap and selftest callbacks to match the new
type.

Continue to use ptep_get() for software PTE values and set_pte_at() for
updates.
The type remains an alias of pte_t on x86 until that architecture opts in.
