dfu: fill bwPollTimeout and better handle detach
- bwPollTimeout is set to 10 ms, from the DFU spec, this
is the minimum time, in milliseconds, that the host should
wait before sending a subsequent DFU_GETSTATUS request.
Without this, I get 25 seconds value and dfu-util waits twice 25s
during download
- when in IDLE and receiving DETACH, first return 0 to make
dfu-util happy, then use a dfudetach variable to exit dfu
(without an USB reset as per the comment on line 425) and
return to runtime mode.
- tested on i.MX25 & i.MX35 & usb-a926x
