configs: meson64_android: implement recovery boot via BCB

Browse Source 
Right now meson64_android does not know how to boot into Android
Recovery: it simply falls back to "fastboot" mode in the bootloader.

Implement the boot to recovery.
While at it, use the standard BCB way instead of a sm for consistency.
