Pull i2c updates from Wolfram Sang:
"Highlights:
- OF and ACPI helpers are now included in the core, and not in
external files anymore. This removes dependency problems for
modules and is cleaner, in general.
- mv64xxx-driver gains fifo usage to support mv78230
- imx-driver overhaul to support VF610
- various cleanups, most notably related to devm_* and CONFIG_PM
usage
- driver bugfixes and smaller feature additions"

I2C of helpers used to live in of_i2c.c but experience (from SPI) shows
that it is much cleaner to have this in the core. This also removes a
circular dependency between the helpers and the core, and so we can
finally register child nodes in the core instead of doing this manually
in each driver. So, fix the drivers and documentation, too.

If the 'failed to find codec platform device' error path is executed, it should
jump to 'fail' label instead of returning an error immediately.
'fail' label will then free the ssi_np and codec_np previously acquired nodes.

This is the initial imx-wm8962 device-tree-only machine driver working with
fsl_ssi driver. More features can be added on top of it later.
