drm/amd: Forbid suspending into non-default suspend states
On systems that default to 'deep' some userspace software likes
to try to suspend in 'deep' first. If there is a failure for any
reason (such as -ENOMEM) the failure is ignored and then it will
try to use 's2idle' as a fallback. This fails, but more importantly
it leads to graphical problems.
Forbid this behavior and only allow suspending in the last state
supported by the system.
