docs: driver-api: add a series of orphaned documents
There are lots of documents under Documentation/*.txt and a few other orphan documents elsehwere that belong to the driver-API book. Move them to their right place.

-===================================================================
-A driver for a selfmade cheap BT8xx based PCI GPIO-card (bt8xxgpio)
-===================================================================
-
-For advanced documentation, see http://www.bu3sch.de/btgpio.php
-
-A generic digital 24-port PCI GPIO card can be built out of an ordinary
-Brooktree bt848, bt849, bt878 or bt879 based analog TV tuner card. The
-Brooktree chip is used in old analog Hauppauge WinTV PCI cards. You can easily
-find them used for low prices on the net.
-
-The bt8xx chip does have 24 digital GPIO ports.
-These ports are accessible via 24 pins on the SMD chip package.
-
-
-How to physically access the GPIO pins
-======================================
-
-The are several ways to access these pins. One might unsolder the whole chip
-and put it on a custom PCI board, or one might only unsolder each individual
-GPIO pin and solder that to some tiny wire. As the chip package really is tiny
-there are some advanced soldering skills needed in any case.
-
-The physical pinouts are drawn in the following ASCII art.
-The GPIO pins are marked with G00-G23::
