arm64: dts: rockchip: Add ArmSoM CM5 and CM5-IO

Add the ArmSoM CM5, an RK3576 compute module (rk3576-armsom-cm5.dtsi),
and its CM5-IO carrier (rk3576-armsom-cm5-io.dts). The module has the
RK806 PMIC, HYM8563 RTC, eMMC, GMAC0 with an on-module MotorComm YT8531
PHY, and the SDIO bus for the on-module WiFi. The carrier adds HDMI, a
GbE RJ45, two USB-A ports behind a USB3 hub, USB-C with FUSB302 and DP
alt-mode, a PCIe 2.0 x1 M.2 slot, microSD, status LEDs and a 40-pin
header.

The YT8531 has no crystal and takes the SoC 25 MHz reference
(REFCLKO25M_GMAC0_OUT), described as a clock on the PHY node and enabled
by the PHY driver. The PHY is named explicitly so it is instantiated
from the device tree without an MDIO ID probe, which the PHY cannot
answer until that clock is running. Its reset is described at the MDIO
bus level so mdiobus releases it before the scan.
