usb: musb: fix oops on musb_gadget_pullup
an 'unhandled fault' is causes when a gadget driver calls
usb_gadget_connect() while the USB cable isn't plugged into
the OTG port.
the fault is caused by an access to MUSB's memory space
while its clock is turned off due to pm_runtime kicking
in.
in order to fix the fault, we enclose musb_gadget_pullup()
with pm_runtime_get_sync() ... pm_runtime_put() calls to
be sure we will always reach that path with clock turned on.
