[PATCH] Add P1/P2 programmable keys to the sonypi driver.

From: Stelian Pop <stelian@popies.net>

This patch enables sonypi to successfully report P1/P2 programmable keys
events on Sony Vaio Z1 laptops.

Note however that sonypi is unable to distinguish between the two events,
both of them will be reported as SONYPI_EVENT_PKEY_P1, but one event is
better than zero, so there it is.
