remove mentionings of devfs in documentation

Now that devfs is removed, there's no longer any need to document how to
do this or that with devfs.

This patch includes some improvements by Joe Perches.

-DEVFS is the DEVice File System available as an add on package for the
-2.2.x kernels and available as a configuration option in 2.3.46 and higher.
-Devfs allows for the automatic creation and management of device names
-under control of the device drivers themselves.  The Devfs namespace is
-hierarchical and reduces the clutter present in the normal flat /dev
-namespace.  Devfs names and conventional device names may be intermixed.
-A userspace daemon, devfsd, exists to allow for automatic creation and
-management of symbolic links from the devfs name space to the conventional
-names.  More details on devfs can be found on the DEVFS home site at
-<http://www.atnf.csiro.au/~rgooch/linux/> or in the file kernel
-documentation files, .../linux/Documentation/filesystems/devfs/README.

 This is a release version of the driver, but it is impossible to test it
 in all configurations of Linux. If there is any anomalous behaviour that 
 does not match the standard serial port's behaviour please let us know.
