usb: musb: omap2430: Idle musb on init
We want to configure musb state in omap2430_musb_enable() instead of omap2430_musb_init(). Otherwise musb may not idle properly until USB cable has been connected at least once. And we already have omap_musb_set_mailbox() configure mode with omap_control_usb_set_mode() so we can remove those calls from omap2430_musb_enable().
