Input: psmouse - introduce notion of SMBus companions
Prepare PS/2 mouse drivers to work with devices that are accessible both via PS/2 and SMBus, which provides higher bandwidth, and thus suits better for modern multi-touch devices. We expect that SMBus drivers will take control over the device, so when we detect SMBus "protocol" we forego registering input device, or enabling PS/2 device reports (as it usually makes device unresponsive to access over SMBus).
