openrisc: init: Add support for common clk
When testing the new litex_mmc driver it was found to not work on OpenRISC due to missing support for common clk. This patch does the basic initialization to allow OpenRISC to use the common clk framework. Signed-off-by: Stafford Horne <shorne@gmail.com> Reviewed-by: Geert Uytterhoeven <geert@linux-m68k.org>
