sconfig: pass in devicetree filename

Instead of forcing the hardcoded 'devicetree.cb' filename under the
mainboard directory, this allows mainboards to select a filename for
the devicetree file.

This allows mainboard variants that need to use different devicetree
files to live under the same directory.
