[Armbian build PR] - `odroidm1`: de-infest Petitboot 🔥 use Kwiboo's 2023.10-rc2+gmac u-boot

odroidm1: de-infest Petitboot 🔥 use Kwiboo's 2023.10-rc2+gmac u-boot

• odroidm1/edge (rk3568-odroid): bump to 6.4.y, update config, rebase patches to 6.4.10
• odroidm1/edge (rk3568-odroid): bump to 6.5-rc6; manually fix RK808 breakage in .config; rebase patches
  • add patch to remove Petitboot-mandated MTD partitions
    • this way we have access to the full flash, and can write our own u-boot to it
  • rebase all patches
• odroidm1/edge (rk3568-odroid): drop 6.3 and 6.4 patches
• odroidm1: de-infest Petitboot 🔥 use Kwiboo's 2023.10-rc2+gmac u-boot
  • using Kwiboo's rk3568-2023.10-gmac branch with BINMAN-handled blobs
  • patches:
    • boot usb first
    • preboot pci/usb enum/scan
  • usage instructions:
    • build & burn image to SD card
    • insert SD card into board
    • hold the recovery (RCY) button and power on the board
    • watch board boot
    • de-infest Petitboot: use armbian-install to install bootloader to MTD
      • if you don't, you'll need to hold the recovery button every boot
      • optionally: use armbian-install to install OS to eMMC/NVMe/USB
    • power-off board
    • remove SD card (new u-boot always boots SD first!)
    • boot into your newly de-infested machine
      • boot order: USB, SD, MMC, NVME, SCSI (SATA)
  • de-infested machine can now boot (directly) from USB/SATA/NVMe:
    • Armbian UEFI-arm64
    • Fedora 38 aarch64
    • Talos arm64
    • others...
  • extra: new u-boot by Kwiboo (with GMAC patches) gives us stable MAC address
    • although it is based on cpuid#, doesn't match the HK sticker on the board
• odroidm1: update DDR/BL31 blobs; cleanup old Petitboot stuff
  • this depends on https://github.com/armbian/rkbin/pull/20
