Parallel Port Direction Fix
The direction bit in the control register should not be directly
set using PPWCONTROL. The kernel gives the following debug message.
parport0 (ppdev0): use data_reverse for this!
More over setting the data pins to forward mode does not work,
perhaps a bug in the Linux PP driver. The right way to do this is
to use PPDATADIR to set the direction. The patch checks if the
user is toggling the direction bit, and invokes PPDATADIR to
do the job.
