In case the ops is not implemented, return 0 in the core right away. This is better than having multiple copies of functions which just return 0 in each power domain driver. Drop all those empty functions. Signed-off-by: Marek Vasut <marex@denx.de> Cc: Patrick Delaunay <patrick.delaunay@foss.st.com> Cc: Simon Glass <sjg@chromium.org>
