These scripts have not seen the necessary changes to keep them up to
date with current KPIs and coding practices. They use I/O ports directly
rather than any bus abstractions, use i386 (which is on the way out for
kernel configs) as the architecture of choice for generated kernel
configs, use ISA KPIs, use INTR_TYPE_FAST (renamed in 2000 to INTR_FAST
and removed in 2011), and likely have other issues too that render them
more harm than good for the uninitiated developer looking for a driver
template. If anyone wants to invest time in modernising them they can do
so and bring them back, but for now delete them.
