description:
apply some of the additional changes from Arto Huusko in PR#49645:
- call pmf_device_deregister on detach.

i've kept the "resume = true" for radeon_resume_kms() call as it
seems to work for me (indeed, code inspection shows it is unused
on netbsd :-)

my old nforce4 box that can resume old drm (or could, last i tried
several years ago) while X and GL apps were running, can at least
survive a resume if X hasn't started.  my one attempt so far with
X exited, but having run, did not work.
