kbuild: always run gcc -E on *.dts, remove cmd_dtc_cpp
Replace cmd_dtc with cmd_dtc_cpp, and delete the latter. Previously, a special file extension (.dtsp) was required to trigger the C pre-processor to run on device tree files. This was ugly. Now that previous changes have enhanced cmd_dtc_cpp to collect dependency information from both gcc -E and dtc, we can transparently run the pre- processor on all device tree files, irrespective of whether they use /include/ or #include syntax to include *.dtsi.
