Mattijs Korpershoek b749d5ecdc configs: meson64_android: define raw parts for bootloader
Per the android documentation[1]:
- the mmc2boot0 partition should be labeled "bootloader".
- the mmc2boot1 partition should be labeled "bootenv".

Also the u-boot documentation[2] refers to a BOOT1_OFFSET of 1 block.

Define 2 raw partitions to store the bootloaders and the bootenv.
