<br>
Would you please help review the change?<br>
<br>
Thanks,<br>
Hersen<br>
<br>
<br>
<br>
<br>
<br>
[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.<br>
<br>
current dal sequence for dcn1_update_clock to pplib:<br>
<br>
1.smu10_display_clock_voltage_request for dcefclk 2.smu10_display_clock_voltage_request for fclk 3.phm_store_dal_configuration_data {<br>
  set_min_deep_sleep_dcfclk<br>
  set_active_display_count<br>
  store_cc6_data --- this data never be referenced<br>
<br>
new sequence will be:<br>
<br>
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<br>
<br>
after this code refactor, smu10_display_clock_voltage_request,<br>
phm_store_dal_configuration_data will not be needed for rv.<br>
<br>
[HOW] step 1: add new functions at pplib interface<br>
      step 2: add new functions at amdgpu dm and dc<br>
