USB: move many drivers to use DEVICE_ATTR_WO
Instead of "open coding" a DEVICE_ATTR() define, use the
DEVICE_ATTR_WO() macro instead, which does everything properly instead.
This does require a few static functions to be renamed to work properly,
but thanks to a script from Joe Perches, this was easily done.
