HID: fix mismatch between hid-input HUT find/search mapping and the HUT

HID: fix mismatch between hid-input HUT find/search mapping and the HUT

When comparing usb vs ps2 / testing the keycodes generated for the easy access
keys on my trust (microsoft compatible) keyboard. I noticed the search key
generated the keycode for find when connected through USB. This lead me to
check the consumer page mappings in hid-input.c . And it turns out the the
mapping for ID 0x221 deviates from the HUT standard document:
http://www.usb.org/developers/devclass_docs/Hut1_12.pdf

Currently it is incorrectly mapped to find, whereas it should be mapped to
search. I also added missing bindings for ID 0x21f, the real find and for
0x222, goto.
