Aidan MacDonald a5b08d0af7 Shanling Q1: Support OF-initiated firmware updates
It's now possible to install OF updates on a rockboxed Shanling Q1.
Previously these didn't work because the RB bootloader interrupted
the update process.

Updates will proceed as they normally do on a non-Rockboxed Q1,
except at the end of the update you'll reboot to Rockbox instead
of the OF. This is only a minor inconvienience and doesn't affect
the update process.
