ide: skip probing port if "hdx=noprobe" was used for both devices on it

* Skip probing port if "hdx=noprobe" parameter was used for both devices on it.

* Obsolete "idex=noprobe" parameter - it only works for ide_generic, cmd640
  and PCI hosts in Compatibility mode (on alpha/x86/ia64/m32r/mips/ppc32).
