Hello Lance Zhao, build bot (Jenkins), Nico Huber, Tim Wawrzynczak, Maximilian Brune, Lean Sheng Tan, Werner Zeh, Jan Samek,

acpigen: Add a runtime method to override exposed _Sx sleep states

This allows mainboards to override available sleep states at runtime.
This is done by adding a IntObj in SSDT that DSDT consumes to override
the available _Sx states.
