Pull the model data (register addresses/sizes) out of the different model files and into the machs.h header. The models themselves don't care about where they're mapped, only the mach code does. This allows us to keep the model headers from being included in the mach code which can cause issues with model-specific names colliding. Such as when a newer device model is created, but with incompatible register names/layouts. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
