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.
