[PATCH RESEND] usb: musb: omap: fix crash when musb glue (omap) gets initialized

[Kishon Vijay Abraham I <kishon@ti.com>]

Upstream Commit: 7acc6197b76edd0b932a7cbcc6cfad0a8a87f026
Upstream Kernel Tag: v2.6.38-rc5-94-g7acc619

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.
