feat: add support for Orange Pi 3B

[timoguin]

This adds support for the Orange Pi 3B (v2.1). This should allow
booting from NVMe, as well as SD Card or eMMC. This still needs to
be tested.

This is mostly inspired by the Radxa Zero 3E support, as they both
use the same RK3566 SoC.

Changes:

• Add orangepi-3b build profile
• Add u-boot-rockchip-spi.bin to Orange Pi 3B artifacts
• Installer implementation with DTB and u-boot setup
• Documentation updates

Signed-off-by: Tim O'Guin timoguin@ohollow.tech

Todo

• Figure out why network interface does work

Hey, @frezbo. I was planning on using imager to do a full end-to-end test, but I've not had a chance to figure out how to use it yet. I can test after merging if that's acceptable.

please test with imager, https://docs.siderolabs.com/talos/v1.12/platform-specific-installations/boot-assets#example:-raspberry-pi-overlay-with-imager see on how to build a disk image

Okay, I was able to build with imager and test booting from SD card. Booting works, including video output, but there is an issue with the network interface not coming up. The link goes up and down in a loop and never receives an IP address.

From my searching, this is a common issue with anything not using the vendor-supported BSP kernel.

I marked this as a draft and will dig into some more when I have the time.
