We are preparing for Xe driver. Backing object implementation is differing
between i915 and Xe. Split i915 specific code into separate source file
built only for i915.

v5:
  - Keep drm_any_plane_has_format check in intel_fb.c
  - Use mode_cmd instead of user_mode_cmd for intel_fb_bo_lookup_valid_bo
v4: Move drm_any_plane_has_format check into intel_fb_bo.c
v3: Fix failure handling in intel_framebuffer_init
v2: Couple of fixes to error value handling
