MFC r322287 (mw): Add support for "compatible" parameter in ofw_fdt_fixup
Sometimes it's convenient to provide fixup to many boards
that use the same SoC family (eg. Marvell Armada 38x).
Instead of putting multiple entries in fdt_fixup_table,
use one entry which refers to all boards with given SoC.
