drm/amdkcl: increase drm vma offset size limit
For 8 processes share 256GB system memory application case, 1T Bytes drm
vma offset limit is not big enough. Increase the limit to 16TB, for max
44bits address space because the upper bit is encoded with gpu_id.
Remove the 64GB size condition check to handle all kernels, 64GB is
Ubuntu kernel default setting, CentOS, Redhat kernel default is 1TB.
