[WHY & HOW]
Driver disable will deallocate framebuffer to reset IPS state, this will cause IPS start with
INIT state to blindly power gate ONO region to break power sequence. All the gating blocks
should be powered up when releasing hw to ensure all the power optimizations are identical to pre-OS.

[Why]
Seamless boot skips MPC init for the active pipe, resulting in stale MPC
rate control state being retained. This will cause issues since other
logic assumes it is disabled (as DCN30 and newer does not need it).
[How]
Disable MPC rate control on ODM pipe update to cover the seamless boot
case.

[Why]
Dropping the entirety of dml2_policy_build_synthetic_soc_states exposes
an issue for states that cannot be filled via bbox_overrides and rely on
the default parameters that may or may not be present depending on the
DM.
For amdgpu_dm this results in missing parameters for most of the struct
in higher states:
- sr_exit_time_us
- sr_enter_plus_exit_time_us
- sr_exit_z8_time_us
- sr_enter_plus_exit_z8_time_us
- urgent_latency_pixel_data_only_us
- urgent_latency_pixel_mixed_with_vm_data_us
- urgent_latency_vm_data_only_us
- dram_clock_change_latency_us
- fclk_change_latency_us
- usr_retraining_latency_us
- writeback_latency_us
- urgent_latency_adjustment_fabric_clock_component_us
- urgent_latency_adjustment_fabric_clock_reference_mhz
- dscclk_mhz
- phyclk_mhz
- phyclk_d18_mhz
- phyclk_d32_mhz
- use_ideal_dram_bw_strobe
[How]
Copy from the first state, applying a minimal policy to set max clocks
for SOC independent values.
Then copy the SOC dependent ones from the states modified by
bbox_overrides.

[Why]
DMColor inaccurately updates color space, bias and scale
destructively in dc_plane_state. This can be resolved by
accurately populating the infos on dc_plane_info where then
translation to plane state can happen as a whole surface update sequence.

Remove dc_plane_state update in DMColor and update color space,
bias and scale on dc_plane_info.

[WHY]
Right now in dml2 mode validation we are calculating UBF parameters for
prefetch calculation for single and dual DPP scenarios. Data structure
to store such values are just 1D arrays, the single DPP values are
overwritten by the dualDPP values, and we end up using dualDPP for
prefetch calculations twice (once in place of singleDPP support check
and again for dual).
This naturally leads to many problems, one of which validating a mode in
"singleDPP" (when we used dual DPP parameters) and sending the singleDPP
parameters to mode programming, if we cannot support then we observe the
corruption as described in the ticket.
[HOW]
UBF values need to have 2d arrays to store values specific to single and
dual DPP states to avoid single DPP values being overwritten. Other
parameters are recorded on a per state basis such as prefetch UBF values
but they are in the same loop used for calculation and at that point its
fine to overwrite them, its not the case for plain UBF values.
