[PATCH V2] i2c: i801: Adding Intel Lewisburg support for iTCO

[PATCH V2] i2c: i801: Adding Intel Lewisburg support for iTCO

[Alexandra Yates]

Starting from Intel Sunrisepoint (Skylake PCH) the iTCO watchdog
resources have been moved to reside under the i801 SMBus host
controller whereas previously they were under the LPC device.

This patch adds Intel lewisburg SMBus support for iTCO device.

Yes, Alexandra, please always include a changelog (between the ---
separator and the diffstat) when posting patch updates.

In this case there is no code change, the only change is the subject.

If I understand correctly, this is a fixup for commit
cdc5a3110e7c3ae793f367285789a6bc39c962dc ("i2c: i801: add Intel
Lewisburg device IDs") which should have included these changes. If so,
please mention it in the commit message. It may also make sense to tag
the patch for stable [v4.4].

It is an addition to that commit, at the time I submitted the commit I 
wasn't aware that this portion was needed to load dynamically since this 
part of the code was in flux as well.  As it is the driver loads using 
modprobe. I'll add that to the commit message to make it clear and 
resend the patch.

The subject line changed I added i2c:i801 per your past request to match 
the subject format for the list.
