ide: remove obsoleted "idex=base[,ctl[,irq]]" kernel parameters (take 2)

Browse Source 
* 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.

@@ -71,29 +71,6 @@ This driver automatically probes for most IDE interfaces (including all PCI
ones), for the drives/geometries attached to those interfaces, and for the IRQ
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.
The IDE driver automatically detects and handles this. However, this may
