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. Change-Id: I0f8fc96f073c50c1512bf60e0927491be8178eb0
