ide: remove obsoleted "idex=base[,ctl[,irq]]" kernel parameters (take 2)
* Remove obsoleted "idex=base[,ctl[,irq]]" kernel parameters
and update Documentation/ide/ide.txt.
* Remove no longer needed ide_forced chipset type.
v2:
* is_chipset_set[] -> is_chipset_set in ide.c.
* Documentation/ide/ide.txt fix.

lines being used by the interfaces (normally 14, 15 for ide0/ide1).
-For special cases, interfaces may be specified using kernel "command line"
-options. For example,
-
- ide3=0x168,0x36e,10 /* ioports 0x168-0x16f,0x36e, irq 10 */

-Normally the irq number need not be specified, as ide.c will probe for it:
-
- ide3=0x168,0x36e /* ioports 0x168-0x16f,0x36e */
-
-The standard port, and irq values are these:
-
- ide0=0x1f0,0x3f6,14
- ide1=0x170,0x376,15
- ide2=0x1e8,0x3ee,11
- ide3=0x168,0x36e,10
-
-Note that the first parameter reserves 8 contiguous ioports, whereas the
-second value denotes a single ioport. If in doubt, do a 'cat /proc/ioports'.

-In all probability the device uses these ports and IRQs if it is attached
-to the appropriate ide channel. Pass the parameter for the correct ide
-channel to the kernel, as explained above.

Any number of interfaces may share a single IRQ if necessary, at a slight
performance penalty, whether on separate cards or a single VLB card.
