Input: synaptics - split device info into a separate structure
In preparation for SMBus/Intertouch device support, move static device information that we query form the touchpad upon initialization into separate structure. This will allow us to query the device without allocating memory first. Also stop using "unsigned long", everything fits into 32 bit chunks.
