fix trackpad issue

[enrico9034]

After creating Hackintosh on my Dell Latitude 5400, the trackpad did not work. I check the kext directory and I see more Voodoo kext, usually, only one to this kext we need and I check and find which Voodoo type we needed (only PS2) Update this kext and remove all Voodoo kexts we didn't need. Now my Hackintosh trackpad works fine

Just FYI, I did the same thing and had absolutely no issue with trackpad or any other input device despite there being multiple Voodoo kexts present. I don't think this should be comitted into the main branch.
