commit b515dcb0dc4e85d8254f5459cfb32fce88dacbfb upstream.
This commit adds the pixel_clock field to the display config
struct so that power management (DPM) can use it.
We currently don't have a proper bandwidth calculation on old
GPUs with DCE 6-10 because dce_calcs only supports DCE 11+.
So the power management (DPM) on these GPUs may need to make
ad-hoc decisions for display based on the pixel clock.
Also rename sym_clock to pixel_clock in dm_pp_single_disp_config
to avoid confusion with other code where the sym_clock refers to
the DisplayPort symbol clock.

commit 9d73b107a61b73e7101d4b728ddac3d2c77db111 upstream.
This commit is necessary for DC to function well with chips
that use the legacy power management code, ie. SI and KV.
Communicate display information from DC to the legacy PM code.
Currently DC uses pm_display_cfg to communicate power management
requirements from the display code to the DPM code.
However, the legacy (non-DC) code path used different fields
and therefore could not take into account anything from DC.
Change the legacy display code to fill the same pm_display_cfg
struct as DC and use the same in the legacy DPM code.
To ease review and reduce churn, this commit does not yet
delete the now unneeded code, that is done in the next commit.
v2:
Rebase.
Fix single_display in amdgpu_dpm_pick_power_state.
