From the runtime callbacks enable hwmod wakeups for uart which will internally enable io-pad wakeups for uarts if they have rx-pad pins set as wakeup capabale. Use the io-ring wakeup mechanism after uart clock gating and leave the PM_WKST set for uart to default reset values cleanup the code in serial.c which was handling PM_WKST reg. Irq_chaing(PRM_DRIVER) is used to wakeup uart after uart clocks are gated using pad wakeup mechanism.
