refactor(tc): add platform specific DT files

Browse source 
Currently, the DT binding uses the file 'tc.dts' as a central place for
all TC platforms. And the variables (for different platforms, or FVP vs
FPGA, etc.) are maintained in 'tc_vers.dtsi'.

This patch renames 'tc.dts' to 'tc-base.dtsi' and creates an individual
.dts file for every platform. The purpose is to use 'tc-base.dtsi' for
maintaining common DT binding and every platform's specific definitions
will be moved into its own .dts file. This is a preparation for
sequential refactoring.

It changes to include the header files in platform DTS files but not in
the 'tc-base.dtsi'. This can allow 'tc-base.dtsi' is general enough and
platform DTS files covers platform specific defintions.
