From: Alan Chiang <alanx.chiang@intel.com>
The AT24 series chips use 8-bit address by default. If some chips would like to support more than 8 bits, the at24 driver should be added the compatible field for specfic chips.
Provide a flexible way to determine the addressing bits through address-width in this patch.

--- since v1: -- Remove the address-width field in the example. since v2: -- Remove redundant space. since v3: -- Add Acked-by.
