HID: refactor mapping to input subsystem for quirky devices

Currently, the handling of mapping between hid and input for devices
that don't conform to HUT 1.12 specification is very messy -- no per-device
handling, no blacklists, conditions on idVendor and idProduct placed
all over the code.

This patch moves all the device-specific input mapping to a separate
file, and introduces a blacklist-style handling for non-standard
device-specific mappings.
