ERRCONFIG register's VPBOUNDINTST has an additional functional meaning
It force clears Sr_interruptz internal signal. This can result in
scenarios where VP->  SR protocol is violated where voltage processor's
As interruptz is already high, VP will never clear the signal vpirqclr.
Therefore during the next force update to reset to nominal voltage,
VP can’t pulsed vpirqclr =>  PRCM HW can’t generate the tranxdone IRQ
and the situation is not recoverable untill a cold reset is invoked.

To prevent this situation, check if status is set before clearing the
status as this needs to be done only on a need basis.
