Paired bluetooth mice irregularities after resume from suspend

[Juan Martinez]

System model: Dell XPS 9370
Killer Wireless 1435
Ubuntu Dell OEM - 18.04.1 LTS

If a Bluetooth device is paired while system is in suspend, upon resuming the system's Bluetooth functionality will intermittently be lost whereas the expectation is the functionality would resume as before.
Bluetooth functionality can be restored by restarting system, entering BIOS, and then exiting BIOS even if nothing is changed.
Standard reboots without entering BIOS will not restore Bluetooth functionality.
Note: Sometimes Wireless is missing as well, but that can be restored through normal reboots without going into BIOS.

Tested on XPS 9370 with Ubuntu 18.04 Dell OEM clean install.
Issue was observed to occur with both of the following devices:
HP x4000b Bluetooth mouse
Logitech G603 Bluetooth mouse

Issue does not seem to occur if system is only allowed to suspend for a short time, issue only occurred if system was left in suspend overnight.

Issue observed to occur both on battery and AC power, power source did not seem to affect the issue.
