Reject modes with a pixel clock higher than the maximum display
clock. Use 400 MHz as a fallback value when the maximum display
clock is not known. Pixel clocks that are higher than the display
clock just won't work and are not supported.
With the addition of the YUV422 fallback, DC can now accidentally
select a mode requiring higher pixel clock than actually supported
when the DP version supports the required bandwidth but the clock
is otherwise too high for the display engine. DCE 6-10 don't
support these modes but they don't have a bandwidth calculation
to reject them properly.

dml21_map_dc_state_into_dml_display_cfg calls (the call is usually
inlined by the compiler) populate_dml21_surface_config_from_plane_state
and populate_dml21_plane_config_from_plane_state which may use FPU. In
a x86-64 build:
$ objdump --disassemble=dml21_map_dc_state_into_dml_display_cfg \
> drivers/gpu/drm/amd/display/dc/dml2/dml21/dml21_translation_helper.o |

Thus it needs to be guarded with DC_FP_START. But we must note that the
current code quality of the in-kernel FPU use in AMD dml2 is very much
problematic: we are actually calling DC_FP_START in dml21_wrapper.c
here, and this translation unit is built with CC_FLAGS_FPU. Strictly
speaking this does not make any sense: with CC_FLAGS_FPU the compiler is
allowed to generate FPU uses anywhere in the translated code, perhaps
out of the DC_FP_START guard. This problematic pattern also occurs in
at least dml2_wrapper.c, dcn35_fpu.c, and dcn351_fpu.c. Thus we really
need a careful audit and refactor for the in-kernel FPU uses, and this
patch is simply whacking a mole. However per the reporter, whacking
this mole is enough to make a 9060XT "just work."

DC can turn off the display clock when no displays are connected
or when all displays are off, for reference see:
- dce*_validate_bandwidth
DC also assumes that the DP clock is always on and never powers
it down, for reference see:
- dce110_clock_source_power_down
In case of DCE 6.0 and 6.4, PLL0 is the clock source for both
the engine clock and DP clock, for reference see:
- radeon_atom_pick_pll
- atombios_crtc_set_disp_eng_pll
Therefore, PLL0 should be always kept running on DCE 6.0 and 6.4.
This commit achieves that by ensuring that by setting the display
clock to the corresponding value in low power state instead of
zero.
This fixes a page flip timeout on SI with DC which happens when
all connected displays are blanked.

-Certain OVT timings require DSC configurations which divide the
horizontal active unevenly across DSC slices
-DSC slices must be even, so padding needs to be added to the active
to make this possible
-The pixel clock of the HW now needs to be increased to accommodate
the extra padded pixels
-To keep the line time the same, the blank of the HW timing needs to
be increased as well
[How]
-Calculate h_active padding, h_total padding, and pixel clock based
off of the original OVT timing and DSC calculations
-Store these values in the pipe and program HW with these modifications
-Added general support for cases where DSC slice config does not evenly
split the horizontal active by fixing some slice width calculations
-Updated PPS calculations for these cases
