[PATCH RFC 2/4] powerpc: Add Microwatt platform

[Paul Mackerras <paulus@ozlabs.org>]

Microwatt is a FPGA-based implementation of the Power ISA.  It
currently only implements little-endian 64-bit mode, and does
not (yet) support SMP.

This adds a new machine type to support FPGA-based SoCs with a
Microwatt core.
