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

Browse Source 
* 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).

As for VLB, it is safest to not specify it.
Bigger values are safer than smaller ones.
"idex=noprobe" : do not attempt to access/use this interface
"idex=base" : probe for an interface at the addr specified,
where "base" is usually 0x1f0 or 0x170
and "ctl" is assumed to be "base"+0x206
