refactor(tc): introduce a new file tc-fpga.dtsi

A Total Compute platform supports FVP and FPGA target. And it's possible
that these two targets have different hardware components. For this
reason, this patch introduces a new file tc-fpga.dtsi for FPGA related
DT binding.

As a result, this patch moves out FVP and FPGA specific macros into
tc-fvp.dtsi and tc-fpga.dtsi respectively.
