Note that for bxt without dmc, display engine can go to lowest
possible state (dc9), so releasing the rpm reference.

I don't think this is needed. We disable all display side runtime power
management if the firmware is not available. So no need to special case
this either imo.
In display off case for broxton platform we can directly goto dc9 state
for which dmc is not needed.
So, don't want to block runtime power management from display side.
