clk: add non CONFIG_OF routines for clk-provider
Some drivers that are shared between architectures have HAVE_CLK selected but don't have OF. To remove compilation errors for drivers that provide clocks on DT with of_clk_add_provider we would have to enclose these calls within #ifdef CONFIG_OF, #endif. This patch adds some stubs for OF related clk-provider functions that either do nothing or return appropriate values if CONFIG_OF is not set. So, definition of these routines will always be available.
