Give the ring functions a separate structure and let the asic
structure point to the ring specific functions. This simplifies
the code and allows us to make changes at only one point.

No change in functionality.

According to the internal teams, we never hit the limit for
mclk switching on these asics, so we can disable the check.

The LCD has a relatively short vblank time (216us), but
the card is able to reclock memory fine in that time.

Disable the UVD block when not in use to save power.
The block is not actually powergated on CI, but we
switch between UVD DPM (where the uvd clocks are
adjusted on demand) and clocks off.

When we PG (powergate) UVD, we need to re-initialize it
before we can use it again.

v2: rebase on UVD stop fixes

Starting on CIK, multi-media blocks like UVD no longer
have special power state.  Rather they have their own
DPM implementation which adjusts their clocks dynamically
when active.  When they are not active, the blocks are
powergated to save power.

v2: add missing pm locks
v3: rebase on uvd state selection rework
v4: fix inverted logic typo noticed by Christian

Check if we can switch the mclk during the vblank time otherwise
we may get artifacts on the screen when the mclk changes.

This adds dpm support for btc asics. This includes:
- dynamic engine clock scaling
- dynamic memory clock scaling
- dynamic voltage scaling
- dynamic pcie gen switching

Set radeon.dpm=1 to enable.
