1cd8b21aa2 drm/radeon/dpm: rework auto performance level enable
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.

Fixes dpm resume on SI.

aa842d736e drm/radeon: gcc fixes for rv6xx dpm
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.

b841ce7b41 drm/radeon/dpm: fix spread spectrum setup (v2)
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.

fixes some systems reported here:

v2: fix typo

2333a003a8 drm/radeon/dpm: fix displaygap programming on rv6xx
Need to use the driver state rather than the register
state since the displays may not be enabled when the
power state is programmed.
