Alex Deucher e14cd2bbcb drm/radeon/dpm: switch on new late_enable callback 
Right now it's called right after enable, but after
reworking the dpm init order, it will get called later
to accomodate loading the smc early, but enabling
thermal interrupts and block powergating later after
the ring tests are complete.
