If we enter at __setup_cpu_440grx we'll return to some bogus

This adds cpu_setup functionality to PowerPC 44x platform.
The cpu_setup callback is invoked by head_32 code and
the identify_cpu() function at early init and is used to
initialize FPU on 440EP(x) processors. The FPU initialization
was previously done in head_44x.S. Also a workaround for
the in
