Merge branch '2023-04-04-android-image-v3-v4-support'

To quote the author:
* This is based on Roman Stratiienko's work to support boot image header version 3 and 4.

* This supports the new boot image headers v3, v4 and bootconfig feature.
https://source.android.com/docs/core/architecture/bootloader/boot-image-header
https://source.android.com/docs/core/architecture/bootloader/implementing-bootconfig

- Tested on Amlogic Khadas vim3l, a reference board for Android Open Source Project
  https://www.khadas.com/vim3l

  And on AM625 Texas Instruments board with 5.10 linux kernel

Main changes :
- New partition : vendor boot, with a specific vendor ramdisk
- DTB is stored in the vendor boot partition
- The generic ramdisk is placed after the vendor ramdisk
- Bootconfig feature support
