From: Gene Chen <gene.chen@intel.com>

commit 963cb6fa0f5f115986e970b9d97440e4906524fa upstream.

Add support for Leon touch devices, which is the same as
falco/peppy/wolf on the same buses using the LynxPoint-LP I2C
via the i2c-designware-pci driver.

Based on these patches from the chromeos-3.8 kernel:
