OMAP2420: clock: use autoidle clkops for all autoidle-controllable interface clocks 

Mark each interface clock with a corresponding CM_AUTOIDLE bit with
a clkops that has the allow_idle/deny_idle function pointers populated.
This allows the OMAP clock framework to enable and disable autoidle for
these clocks.
