Subject[PATCH] Allow number of IDE interfaces to be selected (X86)
A small patch I done to allow X86 users to select the max number of IDE 
interfaces they have - this eliminates the need for passing idex=noprobe on
the command line and/or stops the needless probes at boot on non-existant IDE

I have done this as I assume the majority of X86 users will only have 2 IDE
interfaces, and therefore it allows the option to specify this.

ALPHA and SUPERH users need to select this to continue as per the way it works
for them.

For X86 people, not selecting this allows the kernel to use the defaults 'as

This is the maximum number of IDE hardware interfaces that will

the number of IDE interfaces in your system.
