[PATCH] sonypi: rework input support 

 * feed most of special keys through the input subsystem
 * initialize two separate input devices: a mouse like one for
   the jogdial and a keyboard like one for the special keys
 * add support for SONYPI_EVENT_FNKEY_RELEASED

Many people participated in a way or another to this patch, 
including Daniel K. <daniel@cluded.net>, Bastien Nocera <hadess@hadess.net>,
Dmitry Torokhov <dtor@mail.ru> and Vojtech Pavlik <vojtech@suse.cz>.
