Changes:
- use boot.img instead of boot_fit.img
- use .dtb from boot.img v2
- implement recovery boot
- always boot ramdisk from boot.img, we can't mount system as root
now, as system is a logical partition inside of super partition
- don't add "skip_initramfs" to cmdline anymore
- to boot into recovery, use boot image from recovery partition
- prepare partition table:
- A/B scheme
- use 'super' partition instead of 'system' and 'vendor'
- add dtbo partitions
- introduce metadata partition
Not implemented: reading and applying dtbo blobs from dtbo partition.
