powerpc: Add Microwatt platform
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, VMX, VSX or transactional memory. It has an optional FPU, and an optional MMU (required for running Linux, obviously) which implements a configurable radix tree but not hypervisor mode or nested radix translation. This adds a new machine type to support FPGA-based SoCs with a Microwatt core. CONFIG_MATH_EMULATION can be selected for Microwatt SOCs which don't have the FPU.
