Drop use of drmP.h in remaining .c files.
To ease review a little the drmP.h removal was divided in two commits.

I hate doing this but it hurts my eyes to go over code that does not
comply with indentation rules. Only thing that is not only space change
is in atom.c all other files are space indentation issues.

include radeon_asic.h header file in the various xxx_dpm.c files
to reduce sparse false positive warnings. Not so great patch
in itself, but reducing warning count from 391 to 258 may help
to see real problems..

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.

If the low and high sclks within a power state are the same,
there no need to enable sclk scaling. Enabling sclk scaling
can cause display stability issues on some boards.

Since the clock scaling is based on fb divider adjustments,
make sure the other pll parameters are the same.

Some older 6xx-7xx boards didn't always fill in the
UVD clocks properly in the UVD power states. This
leads to the driver trying to set a 0 clock which
results in slow or broken UVD playback.

Allows you to limit the selected power levels via sysfs.
Force the feedback divider to select a power level.
v2: fix checking in rs780_force_fbdiv,
drop a duplicate divider structure in rs780_dpm_force_performance_level,
Force the voltage level too.

This allows you to look at the current DPM state via
debugfs.
Due to the way the hardware works on these asics, there's
no way to look up exactly what power state we are in, so
we make the best guess we can based on the current sclk.
v2: Anthoine's version
v3: fix ref div

This adds dpm support for rv6xx asics. This includes:
- clockgating
- dynamic engine clock scaling
- dynamic memory clock scaling
- dynamic voltage scaling
- dynamic pcie gen1/gen2 switching
Set radeon.dpm=1 to enable.
v2: remove duplicate line
v3: fix thermal interrupt check noticed by Jerome
