[PATCH v3 4/8] arm64: zynqmp: Add support for Xilinx zcu104-revA

[Michal Simek]

Xilinx zcu104 is another customer board. It is sort of zcu102 clone
with some differences.

Signed-off-by: Michal Simek <michal.simek at xilinx.com>

Changes in v3:
- Use i2c-mux instead of i2cswitch - was done with zcu106
- Remove gpio and usb aliases

Changes in v2:
- Remove i2c mw u-boot commands
- Record compatible string to xilinx.txt
