sparc32_dma: split esp and le into separate DMA devices
Due to slight differences in behaviour accessing the registers for the
esp and le devices, create two separate SPARC32_DMA_DEVICE types and
update the sun4m machine to use.
Note that by using different device types we already know the size of
the register block and the value of is_ledma at init time, allowing us to
drop the SPARC32_DMA_DEVICE realize function and the is_ledma device
property.
