soc/intel/tigerlake: Configure Type-C Input Output Manager(IOM) device
This adds Type-C Intel Input Output Manager(IOM) device with HID INTC1072. It provides MMIO range from 0xfbc10000 with size 0x1600. Intel Input Output Manager(IOM) kernel driver reads relevant information such as Type-C port status (whether a device is connected to a Type-C port or not) and the activity type on the Type-C ports (such as USB, Display Port, Thunderbolt) using this memory resource.
BUG=b:156016218 TEST=Able to detect USB, TBT and USB4 on Volteer.
