dfu: Provide means to find difference between dfu-util -e and -R
This commit provides distinction between DFU device detach and reset.
The -R behavior is preserved with proper handling of the dfu-util's -e
switch, which detach the DFU device.
By running dfu-util -e; one can force device to finish the execution of
dfu command on target and execute some other scripted commands.
Moreover, some naming has been changed - the dfu_reset() method now is known
as dfu_detach(). New name better reflects the purpose of the code.
It was also necessary to increase the number of usb_gadget_handle_interrupts()
calls since we also must wait for detection of the USB reset event.
Example usage:
1. -e (detach) switch
dfu-util -a0 -D file1.bin;dfu-util -a3 -D uImage;dfu-util -e
access to u-boot prompt.
2. -R (reset) switch
dfu-util -a0 -D file1.bin;dfu-util -R -a3 -D uImage
target board reset
