Input: appletouch - add Geyser IV support

Browse source 
The new Core2 Duo MacBook Pro has a new keyboard+trackpad named
"Geyser IV".

According to the Info.plist in the OS X kext, it looks like the Geyser
IV trackpad is identical to the Geyser III trackpad: same IOClass
(AppleUSBGrIIITrackpad), same acceleration tables.
