Seems to work reliably on VI+ except for a few so enable runpm barring
those where baco for runtime power management is not supported.

[rajneesh] Picked https://patchwork.freedesktop.org/patch/335402/ to
enable runtime pm with baco for kfd. Also fixed a checkpatch warning and
added extra checks for VEGA20 and ARCTURUS.

drm/amdkfd: refactor runtime pm for baco

So far the kfd driver implemented same routines for runtime and system
wide suspend and resume (s2idle or mem). During system wide suspend the
kfd aquires an atomic lock that prevents any more user processes to
create queues and interact with kfd driver and amd gpu. This mechanism
created problem when amdgpu device is runtime suspended with BACO
enabled. Any application that relies on kfd driver fails to load because
the driver reports a locked kfd device since gpu is runtime suspended.

However, in an ideal case, when gpu is runtime  suspended the kfd driver
should be able to:

 - auto resume amdgpu driver whenever a client requests compute service
 - prevent runtime suspend for amdgpu  while kfd is in use

This change refactors the amdgpu and amdkfd drivers to support BACO and
runtime power management.

drm/amd/display: Add initialitions for PLL2 clock source

[Why]
Starting from 14nm, the PLL is built into the PHY and the PLL is mapped
to PHY on 1 to 1 basis. In the code, the DP port is mapped to a PLL that was not
initialized. This causes DP to HDMI dongle to not light up the display.

[How]
Initializations added for PLL2 when creating resources.

drm/amd/display: fix workaround for incorrect double buffer register for DLG ADL and TTU

[Why]
these registers should have been double buffered. SW workaround we will have SW program the more aggressive (lower) values
whenever we are upating this register, so we will not have underflow at expense of less optimzal request pattern.

[How]
there is a driver bug where we don't check for 0, which is uninitialzed HW default.  since 0 is smaller than any value we need to program,
driver end up with not programming these registers

drm/amd/display: Add DMUB tracebuffer debugfs

[Why]
The DMUB tracebuffer is useful for understanding DMCUB execution state.

[How]
Add a "show" attribute debugfs so we can loop through the buffer
and print the entries.

The structs for the entry format are defined in the debugfs since
the tracebuffer header no longer exists in the DMUB service.
