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.
