usb: musb: fix oops on musb_gadget_pullup commit 72c487dfb94d02025fb7437dfe2314d836d5a9ab upstream. 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.
