usb: musb: omap: fix crash when musb glue (omap) gets initialized

commit 3006dc8c 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.
