From: Conor Dooley <conor.dooley@microchip.com>

Assorted minor changes to the MPFS/Icicle kit device tree:

- rename serial to mmuart to match microchip documentation
- enable mmuart4 instead of mmuart0
- move stdout path to serial1 to avoid collision with
	bootloader running on the e51
- split memory node to match updated fpga design
- move phy0 inside mac1 node to match phy configuration
- add labels where missing (cpus, cache controller)
- add missing address cells & interrupts to MACs

This is not refactoring. Refactoring could include renames,
hierarchy/layout differences, naming, coding convention. You are
changing features, e.g. using different UART. Please split the changes.

This looks unrelated to refactoring - split of memory - and needs
separate change.

This looks unrelated to refactoring - new modes for MMC - and needs
separate change.

Removal of nodes does not look like refactoring.
