Rajendra Nayak b4777a2138 ARM: OMAP3: clock: Convert to common clk
Convert all OMAP3 specific platform files to use COMMON clk
and keep all the changes under the CONFIG_COMMON_CLK macro check
so it does not break any existing code. At a later point switch
to COMMON clk and get rid of all old/legacy code.
