MIPS: Alchemy: unify CPU model constants.
This patch removes the various CPU_AU1??? model constants in favor of a single CPU_ALCHEMY one. All currently existing Alchemy models are identical in terms of cpu core and cache size/organization. The parts of the mips kernel which need to know the exact CPU revision extract it from the c0_prid register already; and finally nothing else in-tree depends on those any more. Should a new variant with slightly different "company options" and/or "processor revision" bits in c0_prid appear, it will be supported immediately (minus an exact model string in cpuinfo).
