OMAP4: clock: Add dummy clock nodes for interface clocks
On OMAP4 platform the iclk control is completly under hardware control and no software control is available. This difference w.r.t previous OMAP's needs all the common driver accross OMAP's , cpu_is_xxxx() checks. To avoid poulluting the drivers dummy clock nodes are created (The autogeneration script has been updated accordingly).
