[PATCH] sonypi driver update

The most important changes are:
	* add suspend/resume support to the sonypi driver (not
	  based on driverfs however) (Florian Lohoff);
	* add "Zoom" and "Thumbphrase" buttons (Francois Gurin);
	* add camera and lid events for C1XE (Kunihiko IMAI);
	* add a mask parameter letting the user choose what kind
	  of events he wants;
	* use ACPI ec_read/ec_write when available in order to
	  play nice when latest ACPI is enabled;
	* several source cleanups.
