MAINTAINERS: Qualcomm SoC: Match reserved-memory bindings

commit 8b90269ee6d7 ("MAINTAINERS: Split Qualcomm SoC and linux-arm-msm
entries") included an entry for .../bindings/reserved-memory/qcom.
However, it appears that this should have been a glob as although
there are files that start with that path, no file matches that exact
path.

Address this by making the entry a glob.

Flagged by make htmldocs as:
Warning: MAINTAINERS references a file that doesn't exist: Documentation/devicetree/bindings/reserved-memory/qcom
