target-ppc: SPR_BOOKE_ESR not set on FP exceptions
Properly set the book E exception syndrome register when a floating
point exception occurs.
Currently on a book E processor, the POWERPC_EXCP_FP exception handler
fails to set "env->spr[SPR_BOOKE_ESR] = ESR_FP;" as required by the
book E specification.
