drm/amd/display: Program DSC during timing programming

[why]
Link or DIG BE can't be exposed to a higher stream bandwidth than they
can handle. When DSC is required to fit the stream into the link
bandwidth, DSC has to be programmed during timing programming to ensure
this. Without it, intermittent issues such as black screen after S3 or a
hot-plug can be seen.

[how]
Move DSC programming from enabling stream on link to timing setup.

drm/amd/display: Not check wm and clk change flag in optimized bandwidth.

[Why]
System isn't able to enter S0i3 due to not send display count 0 to smu.
When dpms off, clk changed flag is cleared alreay, and it is checked

[How]

values are checked during update to determine whether to perform it, no
need to check it again outside the function.

drm/amdgpu/display: navi1x copy dcn watermark clock settings to smu resume from s3 (v2)

 This interface is for dGPU Navi1x. Linux dc-pplib interface depends
 on window driver dc implementation.

 For Navi1x, clock settings of dcn watermarks are fixed. the settings
 should be passed to smu during boot up and resume from s3.
 boot up: dc calculate dcn watermark clock settings within dc_create,
 dcn20_resource_construct, then call pplib functions below to pass
 the settings to smu:
 smu_set_watermarks_for_clock_ranges
 smu_set_watermarks_table
 navi10_set_watermarks_table
 smu_write_watermarks_table

 For Renoir, clock settings of dcn watermark are also fixed values.
 dc has implemented different flow for window driver:
 dc_hardware_init / dc_set_power_state
 dcn10_init_hw
 notify_wm_ranges
 set_wm_ranges

 For Linux
 smu_set_watermarks_for_clock_ranges
 renoir_set_watermarks_table
 smu_write_watermarks_table

 dc_hardware_init -> amdgpu_dm_init
 dc_set_power_state --> dm_resume

 therefore, linux dc-pplib interface of navi10/12/14 is different
 from that of Renoir.

Swath sizes are being calculated incorrectly. The horizontal swath size

drm/amd/display: fix image corruption with ODM 2:1 DSC 2 slice

[why]
When combining two or more pipes in DSC mode, there will always be more
than 1 slice per line.  In this case, as per DSC rules, the sink device
is expecting that the ICH is reset at the end of each slice line (i.e.
ICH_RESET_AT_END_OF_LINE must be configured based on the number of
slices at the output of ODM).  It is recommended that software set
ICH_RESET_AT_END_OF_LINE = 0xF for each DSC in the ODM combine.  However
the current code only set ICH_RESET_AT_END_OF_LINE = 0xF when number of
slice per DSC engine is greater than 1 instead of number of slice per
output after ODM combine.

[how]
Add is_odm in dsc config. Set ICH_RESET_AT_END_OF_LINE = 0xF if either
is_odm or number of slice per DSC engine is greater than 1.

[why]
When we have single channel memory, we can not light up 2 4k displays
with a 1080p edp, because we don't have enough bw by a small margin.
this small margin comes from dcc meta being too large. We however don't
have this dcc meta when we create fake planes so, before the flip we
will not filter out the mode for 2 4k displays with a 1080p edp

drm/amdgpu: clean wptr on wb when gpu recovery

The TDR will be randomly failed due to compute ring
test failure. If the compute ring wptr & 0x7ff(ring_buf_mask)
is 0x100 then after map mqd the compute ring rptr will be
synced with 0x100. And the ring test packet size is also 0x100.
Then after invocation of amdgpu_ring_commit, the cp will not
really handle the packet on the ring buffer because rptr is equal to wptr.
