Subject: mts-io: add radio-reset-h5 script

radio-reset-h5 is a workaround script to perform a reset of the
H5 radio.

The script disables the USB controller before resetting
the radio and enables it afterward.  If this script is not used
and a radio reset is done with mts-io directly, the radio will not
enumerate properly after reset and will continue to reset itself
indefinitely.
