dts/Makefile: unify cpp/dtc include paths
*.dts may use #include (via cpp) or /include/ (via dtc; assuming a newer
dtc). The choice is up to the creator of the DT. Create a common variable
DTC_INCDIRS that lists the paths searched by include statements, and
update cpp and dtc invocation to use them.
For cpp, also specify -nostdinc to ensure the same set of paths is
available to both type of include statement.
For dtc, create a new DTC_FLAGS variable to hold all the flags passed to
dtc.
