This patch adds the DGNC driver. This is a TTY Serial Port
Driver for the Digi International Neo and Classic PCI based product
line by Digi International <http://www.digi.com>.
This driver isn't hooked up to the build system because it doesn't
build, it merely adds the driver written by Digi to the kernel tree so
that it can be cleaned up and fixed up properly over time.

Current implementation assumes HZ = 1000 for calculating
all internal timer intervals, which creates problem on
platforms where HZ != 1000.
As well we need resolution of less than 10 mSec for heartbeat
calculation, this creates problem on some platforms where HZ is
configured as HZ = 100, or around, which restricts us to timer interval
of 10 mSec. This is particularly found on embedded devices.
This patch moves on to use high resolution timers to calculate
all timer intervals as it allows us to have very small resolution
of timer interval, removing dependency on HZ.

Embedded systems with a PC/104 bus might have a configuration that
does not have ISA enabled. This creates a problem in Comedi where
the PC/104 drivers cannot be enabled.

menu to allow the user to select these drivers on non-ISA systems.
