powerpc: move math-emu over to arch/powerpc
Towards the goal of having arch/powerpc not build anything over in arch/ppc move math-emu over. Also, killed some references to arch/ppc/ in the arch/powerpc Makefile which should belong in drivers/ when the particular sub-arch's move over to arch/powerpc.
