Input: elantech - add support for SMBus devices
Many of the Elantech devices are connected through PS/2 and a different bus (SMBus or plain I2C). To not break any existing device, we only enable SMBus based on a module parameter. If some laptops require the quirk to be set, we will have to rely on a list of PNPIds or MDI matching to individually expose those hardware over SMBus. the parameter mentioned above is elantech_smbus from the psmouse module.
