This series contains some tidy-ups/improvements for the next-cube machine with
the aim of bringing the code up-to-date with our latest coding guidelines.

The main aim of the series is to bring the memory accessors up-to-date with
the memory API and improve some of basic machine modelling. There are still
some future improvements that can be made: for example switching from DPRINTF
macros to trace events and proper modelling of the DMA controller, however
I've left these for now since they allow for easier comparison with Bryce's
original GSoC branch.

This series can be used in conjunction with my upcoming ESP rework series
which fixes up the ESP emulation enough to allow the next-cube machine to
load a kernel from disk and start executing it.
