ARM: dts: msm: Replace all /include/ with #include

To allow the C preprocessor to run on all .dts* files, use
the #include directive instead of /include/. This has been
already added in commit 0cc71c67 ("ARM: dts: msm: Replace
all /include/ with #include") which made this change for
all other msm dts files - do the same for 8916.
