[PATCH 5/7] drm/i915/selftests: use the memcpy_from_wc call from the drm

[Balasubramani Vivekanandan <balasubramani.vivekanandan@xxxxxxxxx>]

memcpy_from_wc functions in i915_memcpy.c will be removed and replaced
by the implementation in drm_cache.c.
Updated to use the functions provided by drm_cache.c.
