soc: qcom: Fix blackghost status irq missing during BG SSR 



BG gpio status irq handler is not calling sometimes due to
enable_irq is clearing gpio intruppt status register, hence gpio
summary irq is not calling status irq handler, with adding delay
also we are seeing issue sometimes, fix it by removing enable_irq.
