[PATCH] ppc32: refactor FPU exception handling
Moved common FPU exception handling code out of head.S so it can be used by several of the sub-architectures that might of a full PowerPC FPU. Also, uses new CONFIG_PPC_FPU define to fix alignment exception handling for floating point load/store instructions to only occur if we have a hardware FPU.
