Kandpal, Suraj Oct. 28, 2024, 7:43 a.m. UTC 
DISPLAY_VER >= 30 onwards CRTC can now support 6k resolution.
Increase pipe and plane max width and height to reflect this
increase in resolution.

--v2
-Take care of the subsampling scenario sooner rather than later [Matt]

--v3
-Take care of the joined pipe limits too [Ankit/Matt]

--v4
-Leave the joiner limits check here as is and handle them later [Ville]
