The approach to allow userspace ~5s to consume the uevent, which is triggered when a new card is inserted/initialized, currently requires the mmc host to support system wakeup. This is unnecessary limiting, especially for an mmc host that relies on a GPIO IRQ for card detect. More precisely, the mmc host may not support system wakeup for its corresponding struct device, while the GPIO IRQ still could be configured as a wakeup IRQ via enable_irq_wake(). To support all various cases, let's simply drop the need for the wakeup support. Instead let's always register a wakeup source and activate it for all card detect IRQs by calling __pm_wakeup_event().
