Elan_i2c and hid-quirks work in conjunction to decide which devices each
driver will handle. Elan_i2c has a whitelist of devices that should be
consumed by hid-quirks so that there is one master list of devices to
handoff between the drivers. Put the ids in a header file so that
hid-quirks can consume it instead of duplicating the list.

I think OF IDs should stay in this file since we agreed HID will not
be checking them.

This just moves the code around. If anything I'd say it should keep
the original Elan copyright.
Thanks.

I thought it would be convenient to keep all the IDs in one place, but
I'll put these back.
