Subject: [RFC PATCH 10/17] powerpc/e500: Fix up the last references to CONFIG_PPC_E500MC

This moves the "select PPC_FPU" from PPC_E500MC to the new FSL_E500MC
processor selection, where it belongs.

The only actual difference that this patch introduces is the P5020DS
board (FreeScale e5500 CPU) will not set FSL_E500MC when building in
64-bit mode.

This is OK as all of the existing code that the 64-bit P5020DS needs is
still conditional on CONFIG_E500 or CONFIG_PPC_FPU, which are both set
properly on the P5020DS (PPC_FPU is always enabled on 64-bit).
