Patrick Delaunay a442e61e24 syscon: update syscon_regmap_lookup_by_phandle ...

Change the function syscon_regmap_lookup_by_phandle()
introduced by commit 6c3af1f24e ("syscon: dm: Add a
new method to get a regmap from DTS") to have
Linux-compatible syscon API.

Same modification than commit e151a1c288 ("syscon: add
Linux-compatible syscon API") solves issue when the node
identified by the phandle has several compatibles and is
already bound to a dedicated driver.

See Linux commit bdb0066df96e ("mfd: syscon: Decouple syscon
interface from platform devices").
