clk: versatile: delete old RealView clock implementation
The old RealView clock implementation is not used anymore (nothing in the kernel calls realview_clk_init()) as we have moved all clocks over to device tree. Delete it. Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>
