[Quantal][PULL] Cypress PS/2 Trackpad driver

[Kamal Mostafa]

This patch set provides a driver for the Cypress PS/2 Trackpad found in
the Dell XPS 13, XPS 15, and other laptop models.

The driver has been tested extensively in the "Sputnik Project" ISO and
kernel PPA.  I have verified that the driver doesn't adversely affect
non-Cypress trackpads by testing various laptops with Synaptics and
Elantech trackpads.

I will submit the driver to mainline on behalf of Cypress, but we'd like
to see it land in Ubuntu sooner rather than later.  SRU for Precise to
follow inclusion in Quantal.

Bug reference:
        https://bugs.launchpad.net/ubuntu/+source/linux/+bug/978807
        'Cypress Trackpad' incorrectly detected as 'ImPS/2 Generic Wheel
        Mouse' in 'Dell XPS 13 Ultrabook'

Thanks,

 -Kamal
