phy: qcom: qmp-combo: Add missing PLL (VCO) configuration on SM8750

Add missing DP PHY status and VCO clock configuration registers to fix
configuring the VCO rate on SM8750.  Without proper VCO rate setting, it
works on after-reset half of rate which is not enough for DP over USB to
work as seen on logs:

  [drm:msm_dp_ctrl_link_train_1_2] *ERROR* max v_level reached
  [drm:msm_dp_ctrl_link_train_1_2] *ERROR* link training #1 on phy 0 failed. ret=-11
