usb: musb: omap: fix crash when musb glue (omap) gets initialized
commit 3006dc8c627d738693e910c159630e4368c9e86c upstream.
pm_runtime_enable is being called after omap2430_musb_init. Hence
pm_runtime_get_sync in omap2430_musb_init does not have any effect (does
not enable clocks) resulting in a crash during register access. It is
fixed here.
