pine64-pinebookpro: deep suspend is broken

Describe your issue

When I close the lid, the device powers down. I cannot confirm if it goes into sleep mode or what exactly. I don't have any daemon that would put the system to sleep when closing the lid, so I'm not sure what's going on.

When I open the lid, the display does not turn back on. The power button won't turn the device back on; I need to hold it for a short while and then press the power button for the device to turn on.

What's the expected behaviour?

Closing the lid should not change the device's power state.

What's the current behaviour?

Closing the lid puts the device into an unknown but unresponsive power state.

How to reproduce your issue?

• Play some music on the device
• Start pinging the device from a different host.
• Close the lid.
  • The music will stop immediately.
  • ping on the other host will stop receiving responses.
• Open the lid.
• The display remains off.
• Pinging the device at this time doesn't work either.

The music and ping stopping at the same time indicate that the device is not still running, so it's not merely the display being off.

Additional information

I tried removing /etc/acpi/PWRF/00000080.

I saw #1179, but in that case the display is turning off and the device keeps responding over the network, so it looks like something different is happening.
