[PATCH 04/11] drivers: i915 selftest: use pgtable_has_pmd_leaves()

[Luiz Capitulino <luizcap@redhat.com>]

igt_can_allocate_thp() uses has_transparent_hugepage() to check if
PMD-sized pages are supported, use pgtable_has_pmd_leaves() instead.

Since igt_can_allocate_thp() wants to use PMD-sized pages with THP,
also check if THP is built-in with IS_ENABLED(CONFIG_TRANSPARENT_HUGEPAGE).
