This patch fixes the DP audio and video PLL configurations for the
zynqmp-zcu102-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.
