[PATCH v2 1/2] cmd: thordown: Add proper dependency for CMD_THOR_DOWNLOAD

[Venkatesh Yadav Abbarapu]

When CONFIG_CMD_USB and CONFIG_USB are disabled some compilation errors are seen as below.

cmd/thordown.o: in function `usb_gadget_initialize':
include/linux/usb/gadget.h:981: undefined reference to `board_usb_init'
cmd/thordown.o: in function `do_thor_down':

Makefile:1779: recipe for target 'u-boot' failed

make: *** Deleting file 'u-boot'

Add dependency of USB_GADGET_DOWNLOAD for CONFIG_CMD_THOR_DOWNLOAD to fix the errors.
