drm/amd/display: Use gpuvm_min_page_size_kbytes for DML2 surfaces

[Why]
It's currently hard coded to 256 when it should be using the SOC
provided values. This can result in corruption with linear surfaces
where we prefetch more PTE than the buffer can hold.

[How]
Update the min page size correctly for the plane.
