docs: admin-guide: add auxdisplay files to it after conversion to ReST
Those two files describe userspace-faced information. While part of it might fit on uAPI, it sounds to me that the admin guide is the best place for them.

+The cfag12864b LCD Series don't have official wiring.
+
+The common wiring is done to the parallel port as shown::

+
+4. Userspace Programming
+------------------------
+
+The cfag12864bfb describes a framebuffer device (/dev/fbX).
+
+It has a size of 1024 bytes = 1 Kbyte.
+Each bit represents one pixel. If the bit is high, the pixel will
+turn on. If the pixel is low, the pixel will turn off.
+
+You can use the framebuffer as a file: fopen, fwrite, fclose...
+Although the LCD won't get updated until the next refresh time arrives.
+
+Also, you can mmap the framebuffer: open & mmap, munmap & close...
+which is the best option for most uses.
+
+Check samples/auxdisplay/cfag12864b-example.c
+for a real working userspace complete program with usage examples.
