arm64: dts: rockchip: rk3566: Add Radxa Compute Module 3 IO

Radxa Compute Module 3(CM3) IO board an application board from Radxa
and is compatible with Raspberry Pi CM4 IO form factor.

Specification:
- 1x HDMI,
- 2x MIPI DSI
- 2x MIPI CSI2
- 1x eDP
- 1x PCIe card
- 2x SATA
- 2x USB 2.0 Host
- 1x USB 3.0
- 1x USB 2.0 OTG
- Phone jack
- microSD slot
- 40-pin GPIO expansion header
- 12V DC

Radxa CM3 needs to mount on top of this IO board in order to create
complete Radxa CM3 IO board platform.

linux-next commit for the same,

commit <8f19828844f2> ("arm64: dts: rockchip: Fix compatible for Radxa
CM3")

Add support for Radxa CM3 IO Board.
