A check is added for avoiding the sleep/wakeup dependency updates
for OMAP4 as the structures for the dependencies are currently absent.

Compiled and Boot Tested on OMAP4430 simulator, ES1 Chip & OMAP3430 SDP.
And also Compiled for OMAP2430 and OMAP2420

This patch has a dependency on the earlier set of OMAP4 clock-domain patches.
