1da37801a8 drm/amd/display: Drop CONFIG_DRM_AMD_DC_DCN2_0 and DSC_SUPPORTED
[Why]

DCN2 and DSC are stable enough to be build by default. So drop the flags.

[How]

Remove them using the unifdef tool. The following commands were executed
in sequence:

$ find -name '*.c' -exec unifdef -m -DCONFIG_DRM_AMD_DC_DSC_SUPPORT -DCONFIG_DRM_AMD_DC_DCN2_0 -UCONFIG_TRIM_DRM_AMD_DC_DCN2_0 '{}' ';'
$ find -name '*.h' -exec unifdef -m -DCONFIG_DRM_AMD_DC_DSC_SUPPORT -DCONFIG_DRM_AMD_DC_DCN2_0 -UCONFIG_TRIM_DRM_AMD_DC_DCN2_0 '{}' ';'

In addition:

* Remove from kconfig, and replace any dependencies with DCN1_0.
* Remove from any makefiles.
* Fix and cleanup NV defninitions in dal_asic_id.h
* Expand DCN1 ifdef to include DCN2 code in the following files:
    * clk_mgr/clk_mgr.c: dc_clk_mgr_create()
    * core/dc_resources.c: dc_create_resource_pool()
    * dce/dce_dmcu.c: dcn20_*lock_phy()
    * dce/dce_dmcu.c: dcn20_funcs
    * dce/dce_dmcu.c: dcn20_dmcu_create()
    * gpio/hw_factory.c: dal_hw_factory_init()
    * gpio/hw_translate.c: dal_hw_translate_init()

0417df1699 drm/amd/display: Isolate DSC module from driver dependencies
[Why]
Edid Utility wishes to include DSC module from driver instead
of doing it's own logic which will need to be updated every time
someone modifies the driver logic.

[How]
Modify some functions such that we dont need to pass the entire
DC structure as parameter.
-Remove DC inclusion from module.
-Filter out problematic types and inclusions

1a9e3d4569 drm/amd/display: Set DSC before DIG front-end is connected to its back-end
[why]
At the time DIG FE is connected to its BE, the clocks in OTG are enabled and
PHY will also be set up. When DSC has to be used to fit the stream into the
available bandwidth, without DSC being set DIG could get exposed to the
higer bandwidth it (or link) could handle. This causes the HW to "reject"
video enable setup (the register shows that video enable was attempted, but
the status bit shows it as disabled).

[how]
- Separate DSC setup into DSC register config and DSC PPS SDP setup

- Move most of the DSC setup (register config) to before
  dcn10_link_encoder_connect_dig_be_to_fe() is  called

- Set up DSC PPS SDP after DIG FE is connected to its BE. This is because
  setting DSC PPS SDP before that has no effect.
