fastboot: Add support for 'reboot fastboot' command
Android 10 adds support for dynamic partitions and in order to support
this userspace fastboot must be used[1]. New tool fastbootd is
included into recovery.
Userspace fastboot works from recovery and is launched if:
1) - Dynamic partitioning is enabled
2) - Boot control block has 'boot-fastboot' value into command field
The bootloader is expected to load and boot into the recovery image
upon seeing boot-fastboot in the BCB command. Recovery then parses the
BCB message and switches to fastbootd mode[2].
Please note that boot script is expected to handle 'boot-fastboot'
command in BCB and load into recovery mode.
Bootloader must support 'reboot fastboot' command which should reboot
device into userspace fastboot to accomodate those changes[3].
Another command that bootloader must support[3] is 'reboot recovery'. This
command should simply reboot device into recovery mode.
