Yes and no.

When clk-mtk.h was removed from the included headers, many headers had
to be added. Also, clk-mux.h did not include any headers, so if it were
to be used by itself, it probably would not compile.

Using forward declarations for the data structures instead of including the
header files inspired in part by that series though.
