Change the function syscon_regmap_lookup_by_phandle() introduced by commit6c3af1f24e("syscon: dm: Add a new method to get a regmap from DTS") to have Linux-compatible syscon API. Same modification than commite151a1c288("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"). Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com> Reviewed-by: Simon Glass <sjg@chromium.org>
