This adds dpm support for KB/KV asics.  This includes:
- dynamic engine clock scaling
- dynamic voltage scaling
- power containment
- shader power scaling

Set radeon.dpm=1 to enable.

Newer asics don't have specific UVD states.
Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

Newer asics have a lot of vram so it's less of an
issue to waste a little more space for the gart
page table.  This gives us some additional gart space
before having to migrate to non-gart system ram
for games, etc. where we use up most of vram.

1. Handle the the thermal state directly in the work handler.
Remove the state selection function since nothing else uses it now.
2. On some asics there is no thermal state, so we just use a regular
state and force the low performance state.

Use the UVD handle information to determine which
which power states to select when using UVD.  For
example, decoding a single SD stream requires much
lower clocks than multiple HD streams.

v2: switch to a cleaner dpm/uvd interface
v3: change the uvd power state while streams
are active if need be

Add a helper function for counting the number of open stream handles.

v2: fix copy-pasta in comments and whitespace error

at the moment
