drm/i915/mtl: end support for set caching ioctl
The design is to keep Buffer Object's caching policy immutable through out its life cycle. This patch ends the support for set caching ioctl from MTL onward. While doing that we also set BO's to be 1-way coherent at creation time because GPU is no longer automatically snooping CPU cache. For userspace components needing to fine tune the caching policy for BO's, a follow up patch will extend the GEM_CREATE uAPI to allow them specify caching mode at BO creation time.
