drm/i915: Add PLANE_CUS_CTL restriction in max_width
PLANE_CUS_CTL has a restriction of 4096 width even though
PLANE_SIZE and scaler size registers supports max 5120.
Take care of this restriction in max_width.
Without this patch, when 5k content is sent on HDR plane
with NV12 content, FIFO underrun is seen and screen blanks
out.
v2: Addressed review comments from Ville. Added separate
functions for max_width - for HDR and SDR
v3: Addressed review comments from Ville. Changed names of
HDR and SDR max_width functions to icl_hdr_plane_max_width
and icl_sdr_plane_max_width
v4: Fixed paranthesis alignment. No code change
