HID: add feature_mapping callback
Currently hid doesn't export the features it knows to the specific modules.
Some information can be really important in such features: MosArt and
Cypress devices are by default not in a multitouch mode.
We have to send the value 2 on the right feature.
This patch exports to the module the features report so they can find the
right feature to set up the correct mode.
