ca6c5e03f1 i2c: intel_i2c: SMBus driver PCI addition (e.g. BayTrail)
This patch adds support for the SMBus block read/write functionality.
Other protocols like the SMBus quick command need to get added
if this is needed.

This patch also removed the SMBus related defines from the Ivybridge
pch.h header. As they are integrated in this driver and should be
used from here. This change is added in this patch to avoid compile
breakage to keep the source git bisectable.

Tested on a congatec BayTrail board to configure the SMSC2513 USB
hub.

2651a052d8 i2c: Drop redundant platform data setting in drivers
The i2c uclass has a default setting for per_child_platdata_auto_alloc_size
so drivers do not need to set it. Remove this from drivers to avoid
confusion.

abb0b01e7a x86: i2c: Add a stub driver for Intel I2C/SMbus
This is used on most Intel platforms. We don't have a driver for it yet, but
add a stub to handle the init. For now this targets ivybridge so we may want
to add a device tree binding and generalise it when other platforms are
supported.
