Code should be consistent.

There is no good reason to have sport->lpuart32 inside sport, but
lpuart_is_be outside of it. Both these values describe properties of
particular device, and thus should be in per-device structure.

If that implies adding sport arg to lpuart32_(read|write), just do that.
