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.

74 | For special cases, interfaces may be specified using kernel "command line" | ||
