[PATCH 2/2] arm64: dts: rockchip: Add ArmSoM CM5 and CM5-IO

[Jiaxing Hu <huhuvmb88@gmail.com>]

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 YT8531 PHY and a
SYN43752 WiFi/BT combo; the carrier adds HDMI, GbE, a USB3 hub, USB-C
with FUSB302, PCIe, microSD, ES8388 audio, LEDs and a 40-pin header.

The YT8531 has no crystal, so it uses the SoC 25 MHz clk_mac_refout
output and is reset from the MAC before the MDIO scan.
