ELAN0600 seems to work just fine in mouse emulation mode through i2c-hid,
but to have full raw touch support we need to register it in elan_i2c.ko

Hi,
well, last discussion ended up that the patch was the right solution, so
I am resending it now to get Jiri's ACK so Dmitry will be able to take it.
Just for the sake of it, I double checked the Elan 0x0401 (a i2c-hid device
which might be working with elan_i2c with some tweaks), which I have some
debug logs, and I don't think we will be able to communicate and enable
the raw reporting through HID. So sadly, yes, we need to blacklist in HID
and enable in elan_i2c.
Cheers,
Benjamin
