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.

drm/radeon: gcc fixes for extended dpm tables
...
Newer versions of gcc seem to wander off into the
weeds when dealing with variable sizes arrays in
structs. Rather than indexing the arrays, use
pointer arithmetic.
