[linux-yocto] [PATCH 8/9] i2c: i801: Add support for Intel DNV

[Tan Jui Nee]

From: Mika Westerberg <mika.westerberg at linux.intel.com>

Intel DNV SoC has the same legacy SMBus host controller than Intel
Sunrisepoint PCH. It also has same iTCO watchdog on the bus.

Add DNV PCI ID to the list of supported devices.
