When the kernel starts up, it kicks off compiled-in drivers
that match “compatible” entries it finds in the device tree.
At a later stage (when /lib/modules is available), all kernel modules
that match “compatible” entries in the device tree are loaded.
But if there is no dt table then there should be a fall back path
with which desired kernel modules can be loaded. Hence, add
of_device_id table in the i2c driver to be able to use when there
is no dt table.

Changes in v2:
- Make the commit message appropriate and assign of_match_table
in the driver structure.
