[RESEND PATCH v4 1/2] dt-bindings: at24: Add address-width property
From: alanx . chiang

From: Alan Chiang <alanx.chiang@xxxxxxxxx>
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.
