b9e9f11c91 drm/amd/display: Add debug trace for dmcub FW autoload.
[Why & How]
1. Add trace code enum for easy debugging.
2. Add trace during uC boot up, including loading phy FW
   and dmcu FW.
3. Change cache memory type back to write back,
   since write through has issue when resume from S0i3 100% hang after
   3.2ms.
4. Change CW3 base address to hard code value to avoid memory overlap
   with cw1.
5. Change polling phy init done to infinite loop to avoid dcn hang when
   dmcub uC stalled.
6. Add dmcub FW dis-assembly file to repositatory for debug purpose.

ab16c7363d drm/amd/display: Add DMUB param to load inst const from driver
[Why]
By default we shouldn't be trying to write secure registers during
DMUB hardware init.

[How]
Add a parameter to control whether we put the DMCUB into secure reset
and attempt to load CW0/CW1.

c09eeee4f3 drm/amd/display: Add DMUB service function check if hw initialized
[Why]
We want to avoid reprogramming the cache window when possible.

We don't need to worry about it for S3 but we *do* need to worry about
it for S4 resume.

DM can check whether hardware should be reinitialized or store software
state when going to S4 to know whether we need to reprogram hardware.

[How]
Add helpers to the DMUB service to check hardware initialization state.

DM will hook it up later.

7c008829cd drm/amd/display: Add the DMUB service
The DMUB service is the interface to the DMCUB.

It's required to support Renoir features so it will be enabled and
compiled automatically when the Renoir display engine is enabled via
CONFIG_DRM_AMD_DC_DCN2_1.

DMUB code will initially be guarded by CONFIG_DRM_AMD_DC_DMUB and later
switched to CONFIG_DRM_AMD_DC_DCN2_1 with the config option dropped.
