x86, i8259: Only register sysdev if we have a real 8259 PIC
My platform makes use of the null_legacy_pic choice and oopses when doing
a shutdown as the shutdown code goes through all the registered sysdevs
and calls their shutdown method which in my case poke on a non-existing
i8259. Imho the i8259 specific sysdev should only be registered if the
i8259 is actually there.
Do not register the sysdev function when the null_legacy_pic is used so
that the i8259 resume, suspend and shutdown functions are not called.
