drm/amd/powerplay: rv dal-pplib interface refactor powerplay part
[WHY] clarify dal input parameters to pplib interface, remove
un-used parameters. dal knows exactly which parameters needed
and their effects at pplib and smu sides.
current dal sequence for dcn1_update_clock to pplib:
1.smu10_display_clock_voltage_request for dcefclk
2.smu10_display_clock_voltage_request for fclk
3.phm_store_dal_configuration_data {
set_min_deep_sleep_dcfclk
set_active_display_count
store_cc6_data --- this data never be referenced
new sequence will be:
1. set_display_count --- need add new pplib interface
2. set_min_deep_sleep_dcfclk -- new pplib interface
3. set_hard_min_dcfclk_by_freq
4. set_hard_min_fclk_by_freq
after this code refactor, smu10_display_clock_voltage_request,
phm_store_dal_configuration_data will not be needed for rv.
[HOW] step 1: add new functions at pplib interface
step 2: add new functions at amdgpu dm and dc
