The new OMAP4 IPs introduced a new idle mode named smart-idle with wakeup.
This new idlemode replaces the enawakeup for the new IPs but seems to
coexist as well for some legacy IPs (UART, GPIO, MCSPI...)
Add the new SIDLE_SMART_WKUP flag to mark the IPs that support this
capability.
The omap_hwmod_44xx_data.c will have to be updated to add this new flag.
Enable this new mode when applicable in _enable_wakeup, _enable_sysc and
_idle_sysc.
