MIPS: Alchemy: move commandline mangling out of common code
Not every alchemy-based board might want these options forced on it, and most of this stuff seems to be intended for devboard code anyway. Remove commandline mangling code out of common chip code and instead add relevant sections to all in-tree boards to not change existing behaviour.
