usb: musb-new: omap2430: Reset the MUSB controller early

When booting from USB peripheral boot, the bootrom will not properly deinit the
MUSB controller, which doesn't clearly indicate an USB disconnection to the host
and leaves U-Boot to deal with the state of the previous USB session.

On some host controller drivers (e.g. xhci_hcd), this ends up in a failure
during set address, caused by the lack of proper disconnection notification.

Resetting the controller early in U-Boot notifies the host of the disconnection
and doesn't hurt other use cases.
