superio: Replace D1/D2 power states with D3
Spec says if any object to control the power state exists, at least
D0 and D3 must be supported. And it seems Windows complains about the
missing D3 support: https://ticket.coreboot.org/issues/257
Windows reported `*** STOP: 0x000000A5` with the first parameter
`0x000000000000000D` (refers to a missing ACPI object) and the
third parameter `0x000000003353505F` which is the name of the
object in ASCII, little-endian (`_PS3`).
