It appears more typical to use "-" rather than "_" in the filename to
join SoC and board names.

I guess "_ref" means "reference". Is that how the boards are commonly
known? Are you sure there will never be another reference board for
these SoCs? Given the "model" values in the file, something more like
vt8500-bv07.dts might be more appropriate?

Maybe it's better to just hold off on adding this node, to wait until
the binding is complete so this file doesn't churn? Certainly it sounded
like Sascha was going to change the binding a little in response to
comments it received.
