[PATCH V3] i2c: i801: Adding Intel Lewisburg support for iTCO

[Alexandra Yates <alexandra.yates@linux.intel.com>]

Changes log v2 to v3: Clarified commit message. No changes in code.

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.
It allows to load watchdog dynamically when the hardware is
present.  This patch is an addition
to cdc5a3110e7c3ae793f367285789a6bc39c962dc i2c: i801: "add
Intel Lewisburg device IDs".
