Add ODROID-M1 support (#2387)

* Add ODROID-M1 board support

* Add Rockchip kernel config for ODROID-M1

Kernel defconfig for Rockchip is based on Armbian kernel defconfig
from config/kernel/linux-rk3568-odroid-edge.config (git hash
95c829f9e664).

* Add U-Boot/Kernel patches

* Add Rockchip blob support

Add package which provides Rockchip TPL and ATF firmware binaries.

* Use latest U-Boot for ODROID-M1

* Fix Rockchip blob support

* Update defconfig

* Use GPT by default

* Create uboot partition to support non-recovery boot

* Enable eMMC boot in U-Boot SPL

* Drop unnecessary mmc device selection

Distro boot already activates the right mmc device. The extra selection
seems to actually cause problems for eMMC boot.

* Make sure driver for eMMC is built-in

* Use odroid-m1 as Supervisor machine

* Add ODROID-M1 to CI pipeline and issue template

* Bump to Linux 6.1.16
