The "select USB_GADGET" is not necessary. The PBL part of that driver
doesn't use anything from USB_GADGET.

Without GLOBALVAR selected the USB gadget autostart stuff can be
compiled, but without any functionality, as all functionality is
behind globalvars, so adding this dependency mykes sense.

I am not sure why SYSTEM_PARTITIONS is selected here. Maybe Ahmad can
comment on that. From what I can see with USB_GADGET_AUTOSTART selected
without SYSTEM_PARTITIONS we still get autostart functionality, but
without global.system.partitions support which seems ok.
