It's not a problem, but it's always good to have consistency.  I'm
seeing the guide line below suggests naming of *_dt_match, and
board-omap4panda.c does so.  That's why I did so too.

http://lists.ozlabs.org/pipermail/devicetree-discuss/2011-March/005024.html

But mach-smdkv310.c and codes on devicetree/test are using another
naming scheme *_dt_compat to match the member .dt_compat below.
