Bug description:
[Impact]
TGL systems wake up automatically from s2idle when connecting to a docking
station with a monitor. The wake-up events are generated when BIOS sets
ALL_MONITOR_OFF for power-saving on TGL systems.
[Fix]
A BIOS workaround is used to skip ALL_MONITOR_OFF with an _OSI string
"Linux-Dell-USB4-Wakeup".
[Test]
Verified on Dell's TigerLake platforms
[Regression Potential]
Low. This only works on platforms supporting "Linux-Dell-USB4-Wakeup".
No other platforms will be affected.
