[PATCH v2 2/3] i2c: amd-isp: Initialize unique adpater name

Initialize unique name for amdisp i2c adapter, which is used
in the platform driver to detect the matching adapter for
i2c_client creation.

Add definition of amdisp i2c adapter name in a new header file
(include/linux/soc/amd/isp4_misc.h) as it is referred in different
driver modules.
