Add mainline support for the ArmSoM CM5, an RK3576 compute module, and
its CM5-IO carrier board.

Patch 1 adds the binding, patch 2 the module dtsi and the carrier dts.

The on-module YT8531 PHY has no crystal and needs the SoC 25 MHz
reference clock (clk_mac_refout). Enabling it for RGMII needs a small
dwmac-rk change sent separately to netdev [1]; the clock is optional so
this DTS applies without it.

Tested on a CM5-IO: the YT8531 link comes up at 1Gbps, and RK806,
HYM8563, eMMC, microSD, the USB3 hub and PCIe all probe.
