Hema HK 4f9edd2d7e usb: musb: Fix the crash issue during reboot 
Below crash observed with commit 7acc6197b7
(usb: musb: Idle path retention and offmode support for OMAP3)
during board reboot.

The musb clock was disabled when musb_shutdown() was called by
platform_drv_shutdown in which there are register accesses.
call pm_runtime_get_sync() and pm_runtime_put_sync() in the
musb_shutdown function.
