[PATCH] of/i2c: call i2c_verify_client from of_find_i2c_device_by_node

[Stephen Warren <swarren-3lzwWm7+Weoh9ZMKESR00Q@public.gmane.org>]

From: Stephen Warren <swarren-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>

i2c_bus_type may contain both I2C clients and I2C adapters. Fix
of_find_i2c_device_by_node to call i2c_verify_client to ensure that it
only returns non-NULL of I2C clients.

Note: This is a dependency for the pinctrl I2C bus mux I will send in a
minute. It'd probably be easiest to merge this through the I2C tree.
It might also be useful to put this patch (and the others I'll send) in
a separate tree so it can be merged into any SoC trees that wish to use
this new feature.
