Subject: [PATCH v2 2/8] arm64: zynqmp: Add support for Xilinx zcu100-revC

This board has 2GB of memory, i2c, sd, wifi sdio, spis, uarts, display
port and usbs.
Board is using fixed clocks because clock driver hasn't been merged yet.

Signed-off-by: Michal Simek <michal.simek@...inx.com>
---

Changes in v2:
- Use i2c-mux instead of i2cswitch
- Remove i2c mw u-boot commands
- Use 96boards labels for i2cs and spis
- Fix pmic and wifi node
- Record compatible string to xilinx.txt
- Remove Nathalie's email (she left Xilinx already)
