Patch f8a10ed1 [i2c: mvtwsi: Make address length variable] accidentally
inverted the sequence of address bytes sent to the I2C device. This
patch corrects this by sending the highest byte first and the lowest
byte last again.

Tested on theadorable Armada-XP board.

The nvidia,bpmp property is left over from an old BPMP I2C binding, and
shouldn't be present. Remove it from the SoC DT file, and update the
I2C driver not to parse it; the value wasn't used for anything any more
anyway.

The Tegra I2C binding dictates that the clock name for the Tegra I2C clock
be "div-clk" not "i2c". Fix the Tegra186 DT and I2C driver to honor this.

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.

clk/reset API was tested on T186 platform and previous chip like
T210/T124 will still use the old APIs.

On Tegra186, some I2C controllers are directly controlled by the main CPU,
whereas others are controlled by the BPMP, and can only be accessed by the
main CPU via IPC requests to the BPMP. This driver covers the latter case.
