mfd: syscon: Add syscon_regmap_lookup_by_phandle_optional() function.
This adds syscon_regmap_lookup_by_phandle_optional() function to get an
optional regmap.
It behaves the same as syscon_regmap_lookup_by_phandle() except where
there is no regmap phandle. In this case, instead of returning -ENODEV,
the function returns NULL. This makes error checking simpler when the
regmap phandle is optional.
