ARM: OMAP2+: clock: introduce ti_clk_features flags
This shall be used to replace the cpu type checks around the clock code. Actual bit values will be introduced in patches later. Signed-off-by: Tero Kristo <t-kristo@ti.com> Reviewed-by: Mike Turquette <mturquette@linaro.org> Signed-off-by: Paul Walmsley <paul@pwsan.com>
