[WHY]
Prefetch calculations did not guarantee that bandwidth required in
mode support was less than mode programming which can cause failures.
[HOW]
Fix bandwidth calculations to assume fixed times for OTO schedule,
and choose which schedule to use based on time to fetch pixel data.

[why]
Based on power measurement result, in most cases when display clock
is higher than Vmin display clock, lowering display clock using
dynamic ODM will improve overall power consumption by 0 to 4 watts
even if we can't reach Vmin.

[WHY]
Currently TR0 (trip 0) is not properly budgeting for urgent latency in
DML2.1. This results in overly aggressive prefetch schedules that are
vulnerable to request return jitter, resulting in severe underflow at
the start of the frame.

Forcing 3DLUT DMA check to enable causes urgent latency to be budgeted
properly into the prefetch schedule, avoiding the vulnerability.

[Why]
If we aren't entering RCG/IPS2 or CLKSTOP is not supported by PMFW then
we should be requesting a dispclk value of 0MHz to PMFW.
Currenly we run at max clock since there's an assumption in APU clock
table formulation where we can run at any DISPCLK at any state so the
real clock value ends up as 1200Mhz - the maximum.
[How]
Set to 0 instead of the minimum value in the state array.

[why]
When switching from extended to second display only
mode, the top remote sink is not removed while the top stream
itself is released. This causes DML to think there is no
DP2 output encoder because top remote sink does not match
with the second stream and disables DTBCLK and causes
hang.
[how]
For DP2.0 MST hubs, only treat 1st remote sink as an encoder
only when there are multiple displays connected.

Update coefficients and LUT tables for scaler and sharpener
to improve quality and support different use cases (SDR/HDR)
[How]
Move scaler coefficients to new file dc_spl_scl_easf_filters.c
Remove older coefficients file dc_sp_scl_filters_old.c
Update default taps for EASF support
Update LLS policy for DON'T CARE case
Update cositing offset from 0.5 to 0.25
Add support to adjust sharpness based on level, use case,
and scaling ratio ( using discrete levels )
Apply sharpness to all RGB surfaces and both NV12 and P010
video ( in fullscreen only ). Upscale and 1:1 ratios only
Enable scaler when sharpening 1:1 ratios
Add support for coefficients that are in S1.10 format
(convert to S1.12 format)

The return value from the call to dml21_find_dc_pipes_for_plane() is int.
However, the return value is being assigned to an unsigned int variable
'num_pipes', the condition if(num_pipes <= 0) is not rigorous enough,
so making 'num_pipes' an int.

[Why]
Potential out of bounds access in dml2_calculate_rq_and_dlg_params()
because the value of out_lowest_state_idx used as an index for FCLKChangeSupport
array can be greater than 1.
[How]
Currently dml2 core specifies identical values for all FCLKChangeSupport
elements. Always use index 0 in the condition to avoid out of bounds access.
