8125300088 configs/zynqmp_zcu106_defconfig: uboot dp pll patch
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.

This patch was build and run tested on a zynqmp-zcu106-revA target board.

Upstream-Status: submitted (https://lore.kernel.org/all/62538b4a04dee28a6fc8ac5b85f8c845a5a76aa4.1651740988.git.michal.simek@amd.com/)
This patch will be removed from buildroot in a future release when no longer necessary.
