[Description]
- On init if a display is connected, we need to maintain the DISPCLK
frequency
- Even though DPG_EN=1, the display still requires the correct
timing or it could cause audio corruption (if DISPCLK freq
is reduced)
- Read the current DISPCLK freq and request the same value to ensure
the timing is valid and unchanged
- However, add option to do a full pipe power down (including link)
which will also avoid audio related issues
- Disabled for the time being on dcn32

To enable root clock optimizations, we need a number of
register writes and need to account for the difference
in DPSTREAMCLK between DCN31 and DCN314. To prevent
issues, add a number of register writes to
DCCG_MASK_SH_LIST_DCN314_COMMON(), and define dccg314_init()
which is mostly in alignment with dccg31_init() but
accounts for the new DPSTREAMCLK sequence.

[Why]
The 6.75 GBps link rate is part of the new eDP specification
version 1.5 is going to be supported in the future.
Since this standard is very new and there are no existing 6.75 GBps
panels on the market yet, we should put a condition in the driver
on enabling this feature until we can validate it with real hardware.
[How]
- Add boolean flag support_eDP1_5 in struct dc_debug_options.
- Enable the 6.75 link rate in reduce_link_rate(...) only when
the flag is true.

Observing underflow on dcn30+ system config at 4k144hz
[How]
We set the UCLK hardmax on AC/DC switch if softmax is enabled
and also on boot. While booting up the UCLK Hardmax is set
to softmax before the init sequence and the init sequence
resets the hardmax to UCLK max which enables P-state switching.
Just added a conditional check to avoid setting hardmax on init.

[Why]
DPP Root clock optimization when combined with 4to1 MPC combine results
in the screen turning black.
This is because the DPPCLK is stopped during the middle of an
optimize_bandwidth sequence during commit_minimal_transition without
going through plane power down/power up.
[How]
The intent of a 0Hz DPP clock through update_clocks is to disable the
DTO. This differs from the behavior of stopping the DPPCLK entirely
(utilizing a 0Hz clock on some ASIC) so it's better to move this logic
to reside next to plane power up/power down where we gate the HUBP/DPP
DOMAIN.
The new sequence should be:
Power down: PG enabled -> RCO on
Power up: RCO off -> PG disabled
Rename power_on_plane to power_on_plane_resources to reflect the
actual operation that's occurring.

sequence that better deals with multiple hardware constraints. One of
the improvements is a more reliable sequence for pipe split. Due to the
transition made in version 3.2.226, it should be more reliable to use
the pipe policy as MPC_SPLIT_DYNAMIC, and this commit makes this change.
