arm64: zynqmp: zynqmp-zcu106-revA: Fix DP PLL configuration

Browse source 
This patch fixes the DP audio and video PLL configurations
for the zynqmp-zcu106-revA evaluation board.

The Linux DP driver expects the DP to be using the following PLL config:
  - DP video PLL should use the VPLL (0x0)
  - DP audio PLL should use the RPLL (0x3)

Register 0xFD1A0070 configures the DP video PLL.
Register 0xFD1A0074 configures the DP audio PLL.
