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 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.
