This patch fixes the DP audio and video PLL configurations for the zynqmp-sm-k26-revA som.
It needs to be applied for both the kv260 and kr260 starter kits.
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)
- DP system time clock PLL should use RPLL (0x3)
Register 0xFD1A0070 configures the DP video PLL.
Register 0xFD1A0074 configures the DP audio PLL.
Register 0xFD1A007C configures the DP system time clock PLL.
This patch was build and run tested on a zynqmp-kria-kv260 target board.

This patch is a temporary fix for the kv260 u-boot.itb generation
until a proper fix has been implemented within u-boot.
The problem is u-boot can only be configured to use the kria k26
som dts configuration at build time, and the kv260 carrier board
overlay is missing from the build. Without this, all of the carrier
board drivers are missing.
This patch will be removed from buildroot once u-boot can build a
correct u-boot.itb for the kria kv260 starter kit including the
carrier board overlay and corresponding drivers:

This patch adds support for Xilinx Kria KV260 starter kit.
KV260 features can be found here:
https://www.xilinx.com/products/boards-and-kits/kv260.html
While the Kria SOM is based on a ZynqMP SoC, there are some key
boot config differences from the other ZynqMP evaluation boards.
1. There are no boot switches on Kria SOMs. The boot mode is thus
hard configured for QSPI flash. A pre-programmed boot.bin comes
with every Starter Kit. U-Boot can then find the Linux kernel and
file system on the SD card.
Optional instructions for updating the boot.bin in the QSPI flash
can be found in the readme.txt file and the link below.
https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/1641152513/Kria+K26+SOM
2. Kria SOMs use UART1 for the console instead of UART0. For this
reason, Kria Starter Kits will use a separate extlinux.conf file
from other ZynqMP evaluation boards.

U-Boot SPL configures pinmuxes, clocks and other low-level devices. On
the Xilinx ZynqMP SoCs the code to do this resides in a file called
psu_init_gpl.c which is initially generated by the Xilinx development
tools. Add an option to pass these files from the outside (e.g. in the
board files).
For this to work properly, a patch to U-Boot is needed. However this
patch must be applied by each defconfig using
BR2_TARGET_UBOOT_ZYNQMP_PSU_INIT_DIR. If it were in boot/uboot/ to be
applied unconditionally, it would break the build for configs using a
U-Boot version where the patch is already applied.

In order to boot on the Xilinx ZynqMP SoCs, U-Boot SPL requires a
recent PMU firmware loaded. Instruct U-Boot to add pmufw.bin to the
boot.bin file together with U-Boot SPL, and the boot ROM will load
both.
For this to work properly, a patch to U-Boot is needed. However this
patch must be applied by each defconfig that wishes to use
BR2_TARGET_UBOOT_ZYNQMP_PMUFW. If it were in boot/uboot/ to be applied
unconditionally, it would break the build for configs using a U-Boot
version higher than 2018.7-rc1 where the patch is already applied.
