feat(tc): add device tree binding for TC4

Since TC3 and TC4 share most components in the hardware design, they can
reuse the device tree binding. For this reason, this patch extracts the
common modules from tc3.dts and put into the file tc3-4-based.dtsi.

As a result, a new created tc4.dts file includes tc3-4-based.dtsi for
support DT binding for the TC4 platform.
