The LTC2305 is a 2-channel, 12-bit, fast ADC with an I2C interface,
compatible with the LTC2309 (which has 8 channels).

This patch adds support for the LTC2305 by introducing a chip_info
structure to handle the different channel configurations between the two
variants. The LTC2305 exposes 2 single-ended channels and 2 differential
combinations.

Also updates the device tree bindings to include the lltc,ltc2305
compatible string and documents it in the Kconfig.

There is nothing bad with the series, but hey, ADI, again telling you, deploy
the internal Wiki and put there most of the typical problems with the code
submitted by ADI! This series could be done just in one round, if you do this
and prevent wasting reviewers' time!
