soc/intel/tigerlake: Hook up SMBus device to devicetree
Hook up `SmbusEnable` FSP setting to devicetree state and drop its redundant devicetree setting `SmbusEnable`. The following mainboards enable the SMBus device in the devicetree despite `SmbusEnable` is not being set. * google/deltaur * starlabs/laptop Thus, set it to off to keep the current state unchanged.
