radeon, kdb, kms: Save and restore the LUT on atomic KMS enter/exit
When changing VTs non-atomically the kernel works in conjunction with
the Xserver in user space and receives the LUT information from the
Xserver via a system call. When changing modes atomically for kdb,
this information must be saved and restored without disturbing user
space as if nothing ever happened.
