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

v2: Add boot/dts from the source tree to dtc include path, so that make
O= works; that puts the .dts file that's passed to dtc outside the
source tree, so the include path adjustment is required to find
include files in the source tree.
