[PATCH v2 i-g-t 1/3] lib/xe/xe_mmio: Replace open-coded init/cleanup with existing functions

[Marcin Bernatowicz <marcin.bernatowicz@linux.intel.com>]

Use intel_register_access_init and intel_register_access_fini to handle
initialization and cleanup, reducing code duplication. This improves
maintainability and ensures consistency, including handling forcewake
for Xe.
