This enables suspend/resume support for Pi 5.
The watchdog should be stopped when suspending.
The wireless can be turned off with
cap-power-off-card. It could be left on withkeep-power-in-suspendbut that does not have any benefits currently.NVME drives currently do not work. The NVME driver puts the drive in a low power state and expects the link to be left on. The PCIe driver then turns off the link. This stops the NVME driver waking up the drive. Adding NVME_QUIRK_SIMPLE_SUSPEND to a drive fixes it.
