HID: wiimote: add support for Guitar-Hero devices

Browse Source 
This adds the drums and guitar extensions for Wiimote devices.

Devices are reported as "Nintendo Wii Remote Guitar/Drums". If I ever
get my hands on "RockBand" guitars, I will try to report them via the
same interface so user-space does not have to bother which device it
deals with.

This is a rebase of the original commits 8e22ecb603 and 73f8645db1.
They were reverted several years ago, since they were dependent on the
ABS_* rework of the input core. Sadly, this never worked out so these
commits were never pushed into a release. This rebase now uses the
ABS_HAT* event codes to report all pressure information.
