Input: cyapa - add support for smbus protocol

This patch adds support for the Cypress APA Smbus Trackpad type,
which uses a modified register map that fits within the
limitations of the smbus protocol.

Devices that use this protocol include:
CYTRA-116001-00 - Samsung Series 5 550 Chromebook trackpad
CYTRA-103002-00 - Acer C7 Chromebook trackpad
CYTRA-101003-00 - HP Pavilion 14 Chromebook trackpad
