Calling force_performance_level() from set_power_state()
doesn't work on some asics because the current power
state pointer has not been properly updated at that point.
Move the calls to force_performance_level() out of the
asic specific set_power_state() functions and into
the main power state sequence.

Need to check for engine and memory clock ss separately
and only enable dynamic ss if either of them are found.
This should fix systems which have a ss table, but do
not have entries for engine or memory. On those systems
we may enable dynamic spread spectrum without enabling
it on the engine or memory clocks which can lead to a
hang in some cases.

Need to use the driver state rather than the register
state since the displays may not be enabled when the
power state is programmed.

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
