[PATCH v5 1/3] Input: elan_i2c: Add comment about link between elan_i2c and hid-quirks

[Jeffrey Hugo]

Elan_i2c and hid-quirks work in conjunction to decide which devices each
driver will handle.  Document this link in elan_i2c as a reminder that
updates to elan_i2c need to be mirrored to hid-quirks.
