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.
