Also rename BCM6338 SPI driver to BCM6348 SPI since BCM6338 is a stripped down version of the BCM6348. Switch to devfdt_get_addr_size_index(). v2: Introduce changes requested by Simon Glass: - Always include command bytes when determining max write size. Also move SPI aliases from .dts to .dtsi files.
