dsps_suspend() and dsps_resume() are called with the device that has the
glue assigned as drvdata. Using dev->parent seems wrong and causes a
NULL pointer exception on an AM33xx board.
The code was introduced by commit c68bb4c6 ("usb: musb: dsps: control
module handling (quirk)") but I wonder whether it was ever used.
