From: Alan Chiang <alanx.chiang@intel.com>

Currently the only way to use a variant of a supported model with
a different address with a different address width is to define a
new compatible string and the corresponding chip data structure.

Provide a flexible way to specify the size of the address pointer
by defining a new property: address-width.
