Add initial support for the Radxa Compute Module 5 (CM5). The CM5 uses a
proprietary connector.
Specification:
- Rockchip RK3588
- Up to 32 GB LPDDR4X
- Up to 128 GB eMMC
- 1x HDMI TX up to 8k@60 hz
- 1x eDP TX up to 4k@60 hz
- Gigabit Ethernet PHY

Since the microSD card is on the carrier board, this alias should be
moved to the board DTS.

Most of the other Radxa rk3588 boards have the eMMC alias to mmc0. Why
does this use another convention?

The sdio is not enabled. This alias won't be used.

Should this be left disabled on the SoM dtsi? And only enabled on the
carrier board, if the carrier board has the RJ45 jack?
i.e. a handheld using the CM5 may not have ethernet

Good point, I'll move this to the board DTS. This is a remnant from
copying aspects of the downstream DTS, and adapting it for mainline
conventions.

I think that makes sense, not every carrier is guaranteed to have ethernet.

If you do end up moving the gmac1 enablement to the board, you should
also add an ethernet0 alias at the board level. Mainline does not
define the ethernet0 and ethernet1 aliases at the SoC level, like the
rockchip BSP kernel does (since not all boards will use gmac0 and
gmac1).

You could also enable hdmi0_sound and i2s5_8ch. It's enabled in the
Radxa BSP kernel.
