clk: Add CLK_IS_BASIC flag to identify basic clocks
Most platforms end up using a mix of basic clock types and some which use clk_hw_foo struct for filling in custom platform information when the clocks don't fit into basic types supported. In platform code, its useful to know if a clock is using a basic type or clk_hw_foo, which helps platforms know if they can safely use to_clk_hw_foo to derive the clk_hw_foo pointer from clk_hw. Mark all basic clocks with a CLK_IS_BASIC flag. Signed-off-by: Rajendra Nayak <rnayak@ti.com> Signed-off-by: Mike Turquette <mturquette@linaro.org>
