From: Tony Lindgren <tony@xxxxxxxxxxx>
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().
