Any update to the SRNG TP/HP when the device is in low power state would result in system errors. While in D3 WoW mode, disable EXT grp irqs and drain TXRX before sending enter power save mode to the FW. This will ensure that no interrupts are received while in WoW mode and as a result there wont be any HP/TP updates. Change-Id: Ic1fb7fdd45096b458abf5d243fa652c3da878dc0 CRs-Fixed: 2890568
