[WHY]
DSC block level should only be responsible for reporting single DSC
instance capabilities. Factoring in ODM combine requirements should be
handled in dc_dsc.c. Both components should acquire clocks from clk_mgr
to determine throughput capabilities instead of relying on hard coded
values as these can differ by SoC and SKU.
[HOW]
1) Add dsc_get_single_enc_caps to acquire single DSC instance
capabilities (replacing dsc_get_enc_caps), factoring in DSCCLK
2) add build_dsc_enc_caps to combine single DSC instance capabilities
3) account for max pixel rate per pipe (DISPCLK) when calculating
minimum slice count

[Why]
Previously the 'dsc_bits_per_comp' enumeration was defined in individual
.c files, making it unavailable for other files that may need it.
[How]
The 'dsc_bits_per_comp' enumeration has been relocated to a common header
file.

symbol 'dcn401_dsc_funcs' was not declared. Should it be static?
This symbol is not used outside of dcn401_dsc.c, so marks it static.

DSC was waiting for the wrong field to disconnect cleanly.
[HOW]
Changed field the DSC disconnect was waiting on.

[WHY]
DML2.1 has added the support to determine ODM combine based on DSC slice
count limitation. This support would allow us to support DSC slice higher
than 4 on small timings. The change will allow higher DSC slice support
independent from pixel clock in use.
[HOW]
Add a DCN401 get_enc_caps function to allow the support for DSC slice count
higher than 4.

[why]
Switching between DSC clock or disable DSC block are not double buffered update.
Corruption is observed if these updates happen before DSC double buffered
disconnection.
[how]
Move DSC disable and refclk reset to post unlock update. Wait for DSC double buffered
disconnection and all mpccs are disconnected before reset DSC clock.
