usb: ulpi: add new api functions, {read|write}_dev()

Browse source 
Add these two new api callbacks to struct ulpi_ops. These are different
than read, write in that they pass the parent device directly instead
of via the ops argument.
They are intended to replace the old api functions.

If the new api callbacks are missing, revert to calling the old ones
as before.
