Add ACPI system/device power states properties
Add ACPI system/device power states interface to support
IPMI get/set ACPI state commands.
It is different from existed dbus interface 'PowerState'.
Based on the IPMI spec, this is an independent setting that may not
necessarily match the actual power state of the system.
system power state enumeration:
S0/G0 0x00
S1 0x01
S2 0x02
S3 0x03
S4 0x04
S5/G2 0x05
S4/S5 0x06
G3 0x07
Sleeping 0x08
G1 sleeping 0x09
Override 0x0A
Legacy on 0x20
Unknown 0x2A
Device power state enumeration:
D0 0x00
D1 0x01
D2 0x02
D3 0x03
Unknown 0x2A
