dm: clk: add stub when CONFIG_CLK is deactivated
Add stub for functions clk_...() when CONFIG_CLK is deactivated. This patch avoids compilation issues for driver using these API without protection (#if CONFIG_IS_ENABLED(CLK)) For example, before this patch we have undefined reference to `clk_disable_bulk') for code: clk_disable_bulk(&priv->clks); clk_release_bulk(&priv->clks); Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com>
