soc/amd/common/acpi/upep: Add Low Power State Entry Notifications
Add support to handle S0ix entry and exit notifications by adding the
corresponding _DSM functions. The function indices are chosen based on
the Modern Standby BIOS Implementation Guide 56358 Rev. 1.04. Inside
the notification functions perform any mainboard specific S0ix entry and
exit actions.
BUG=b:195748540
TEST=Build and boot to OS in Guybrush. Ensure that the notification
functions are invoked on S0ix entry and exit. Perform suspend/resume
cycles for multiple iterations.
