Moved, renamed, and deleted files

The original directory structure was scattered and unorganized.
Changes are basically to make it look like kernel structure.

- * 21-Jan-2002 <jco@ict.es> :
- *
- * Added support for synchronous A/D mode. This mode is useful to
- * avoid noise induced in the touchpanel by the LCD, provided that
- * the UCB1x00 has a valid LCD sync signal routed to its ADCSYNC pin.
- * It is important to note that the signal connected to the ADCSYNC
- * pin should provide pulses even when the LCD is blanked, otherwise
- * a pen touch needed to unblank the LCD will never be read.
