[PATCH] ppc32: refactor FPU exception handling

Browse Source 
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.
