This patch will fix the TRITON sleep/wakeup sequence.
Since the function to populate the sleep script is getting called always
irrespective of the flag "TWL4030_SLEEP_SCRIPT", other scripts data
is getting over written by the sleep script.
Print warning if the sleep script is loaded before wakeup script.
Because there is a chance that the Power chip may go to sleep before
the wakeup script is completely loaded, which can cause a system hang.
