block: remove last remaining traces of IDE documentation
The last traces of the IDE driver went away in commit b7fb14d3ac63
("ide: remove the legacy ide driver") but it left behind some traces
of old documentation.
As luck would have it Randy and I would submit similar changes within
a week of each other to address this. As Randy's commit is in the doc
tree already - this delta is just the stuff my removal contained that
was not in Randy's IDE doc removal.

1.3 IDE devices in /proc/ide
|
||||
----------------------------
|
||||
|
||||
The subdirectory /proc/ide contains information about all IDE devices of which
|
||||
the kernel is aware. There is one subdirectory for each IDE controller, the
|
||||
file drivers and a link for each IDE device, pointing to the device directory
|
||||
in the controller specific subtree.
|
||||
|
||||
The file 'drivers' contains general information about the drivers used for the
|
||||
IDE devices::
|
||||
|
||||
> cat /proc/ide/drivers
|
||||
ide-cdrom version 4.53
|
||||
ide-disk version 1.08
|
||||
|
||||
More detailed information can be found in the controller specific
|
||||
subdirectories. These are named ide0, ide1 and so on. Each of these
|
||||
directories contains the files shown in table 1-6.

||||

Each device connected to a controller has a separate subdirectory in the

||||
controllers directory. The files listed in table 1-7 are contained in these
|
||||
directories.
