Trackpad firmware update

[hmuller]

@tllim , @xalius , @ayufan and @anarsoul ,

Just got around to updating the trackpad firmware. The process was simple and did not produce errors. I am writing this with the update applied with the trackpad on, and am not using an external mouse.

I am pleased to report that the palm detection is fixed, it no longer blocks characters from being typed. I still have to keep my meaty thumbs from interacting with the pad though, otherwise I cause inadvertent cursor movement and text selection. It is quite pleasant typing now, even with the trackpad on.

Thanks for this!
