Comment 42 for bug 872833

The flow, goes up to setting PRCM_APE_SOFTRST, after which, the prcmu is suppose to reset all the IP's and then reset the AP.

Workaround given by Robert, just enables the main watchdog timer in ab8500, which later hard-resets the AP9500.

As already discussed, seems to be a prcmu issue to me.(May be debugging needed from prcmu side to tell what happens during reset)
