That looks like it might break !200M. Maybe something line
rinfo->is_mobility && !rinfo->rs480 (with additional modifications to
define an rs480, of course) - or a more generic name indicating why
the rs480 is different?

I know, I am sorry. We could use family as in:

rinfo->is_mobility && rinfo->family != CHIP_FAMILY_RS480

Another solution is to add "default_dynclk" to radeonfb_setup
so that everybody with a rs480 can disable it.

I don't have the register specification for the 200m (RS480) so I don't
know why enabling "dynamic clock pm" doesn't work.
