ARM: OMAP2+: clock: export driver API to setup/get clock features

Browse Source 
As most of the clock driver support code is going to be moved under
drivers/clk/ti, an API for setting / getting the SoC specific clock
features is needed. This patch provides this API and changes the
existing code to use it.
