[PATCH v2] i2c: i801: Add support for Kaby Lake PCH-H

[PATCH v2] i2c: i801: Add support for Kaby Lake PCH-H

[Mika Westerberg]

From: Andy Shevchenko <andriy.shevchenko@linux.intel.com>

Intel Kaby Lake PCH-H has the same legacy SMBus host controller than Intel
Sunrisepoint PCH. It also has same iTCO watchdog on the bus.

Add Kaby Lake PCH-H PCI ID to the list of supported devices.

Changes from v1:
  * Call it Kaby Lake PCH-H instead of Kabypoint
  * Add the device to the list of supported devices in comment on top of
