cmd: bcb: Expose 'bcb_write_reboot_reason' to external callers
Fastboot is evolving and beginning with commit [1], the
upstream implementation expects bootloaders to offer support for:
- reboot-recovery
- reboot-fastboot
The most natural way to achieve the above is through a set of
pre-defined "reboot reason" strings, written into / read from
the BCB "command" field, e.g.:
- bootonce-bootloader [2]
- boot-fastboot [3]
- boot-recovery [4]
Expose the first 'bcb' API meant to be called by e.g. fastboot stack,
to allow updating the BCB reboot reason via the BCB 'command' field.
