drm/i915: Introduce has_media_ratio_mode 



Media ratio mode (the ability for media IP to work at a different frequency
from the GT) is available for a subset of dGfx platforms supporting
GuC/SLPC. Introduce 'has_media_ratio_mode' flag in intel_device_info to
identify these platforms and set it for XEHPSDV and DG2/ATS-M.
