one more queries;

If core_off is enabled and there are devices connected to musb port then
Are we saving the latest register context? I am afraid; we are not saving
and restoring the register context saved during initialization.

To fix this issue, how about calling musb_save/restore functions from arch/arm/mach-omap3/pm34xx.c ? This would be good even for platforms with
USB PHY having no interrupt line.
