CRIS v32: Add new machine dependent files for Etrax-FS and Artpec-3.

The two chips are somewhat different, and needs different handling.
Adds handing of the dma, dram initialization, hardware settings, io,
memory arbiter and pinmux

Also moves the dma, dram initialization and io from CRIS v32 common files.
