drm/i915/display/icl: Bump up the hdisplay and vdisplay as per transcoder limits



On ICL+, the vertical limits for the transcoders are increased to 8192
and horizontal limits are bumped to 16K so bump up
limits in intel_mode_valid()

v4:
* Increase the hdisplay to 16K (Ville)
v3:
* Supported starting ICL (Ville)
* Use the higher limits from TRANS_VTOTAL register (Ville)
v2:
* Checkpatch warning (Manasi)
