drm/amd/display: Limit HW cursor size of >= 4k
[Description]
- For SubVP, we cannot support HW cursor if it's
greater than 64 x 64 x 4 bytes in size
- However, on certain config changes (i.e. pixel format)
we can exit SubVP (then change to HW cursor) then re-enter
SubVP without changing back to SW cursor because there is
no SetCursorAttributes call
- To workaround this issue, limit the HW cursor size to be
less than 64 x 64 x 4 bytes whenever the stream is >= 4K
- Also ensure this W/A only affects DCN that supports SubVP
