x86/fpu: Do system-wide setup from fpu__detect()
fpu__cpu_init() is called on every CPU, so it is the wrong place
to call fpu__init_system() from. Call it from fpu__detect():
this is early CPU init code, but we already have CPU features detected,
so we can call the system-wide FPU init code from here.
