OMAP: hwmod: Set autoidle after smartidle during _sysc_enable

OMAP USBOTG module has a requirement to set the autoidle bit only after
setting smartidle bit. Modified the _sys_enable api to set the smartidle
first and then the autoidle bit. Setting this will not have any impact on the
other modules.
