Hardware-speaking, there is no feature-reduced cursor specific plane, so this driver reserves the last all Overlay plane as a Cursor plane, but sets the maximum cursor width/height to the maximum value that the full overlay plane can use. While this could be ok, it raises issues with common userspace using libdrm (especially Mutter, but other compositors too) which will crash upon performing allocations and/or using said cursor plane. Reduce the maximum width/height for the cursor to 512x512 pixels, value taken from IGT's maximum cursor size test, which succeeds.
