board/zynqmp/zcu106/patches: fix build by dropping U-Boot patch

Since commit
3c997c457a4ee33d81e6b93e4f6f147bb9e861e9 ("configs/zynqmp_zcu106_defconfig:
bump to Xilinx 2022.2"), we're using U-Boot version Xilinx 2022.2,
which already carries the psu_init_gpl.c, causing the build to fail as
our patch doesn't apply.

Fix this by dropping the no longer needed patch.

Fixes: 3c997c457a4ee33d81e6b93e4f6f147bb9e861e9 ("configs/zynqmp_zcu106_defconfig: bump to Xilinx 2022.2")

-Subject: [PATCH 1/1] arm64: zynqmp: zynqmp-zcu102-revA: Fix DP PLL
- configuration
-
-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.
