On ICL+, the max supported plane height is 4320, so bump it up
To support 4320, we need to increase the number of bits used to
read plane_height to 13 as opposed to older 12 bits.
v4:
* Adjust the width mask also since extra bits are mbz (Ville)
v3:
* Use 0xffff for mask as extra bits are mbz (Ville)
v2:
* ICL plane height supported is 4320 (Ville)
* Add a new line between max width and max height (Jose)
