A problem with the logic in upstream_dtsi_include currently is that it
does not list directories such as dts/upstream/src/arm/nxp/imx and so
will not findi "imx6ul-pinfunc.h" for example as it is normally and
correctly included without vendor sub-paths. Expand the current wildcard
glob to catch these directories too.
