Some serial buses like I2C and SPI don't require that the parent device is in D0 before any of its children transitions to D0, but instead the parent device can control its own power independently from the children. This does not follow the ACPI specification as it requires the parent to be powered on before its children. However, Windows seems to ignore this requirement so I think we can do the same in Linux. Implement this by adding a new power flag 'ignore_parent' to struct acpi_device. If this flag is set the ACPI core ignores checking of the parent device power state when the device is powered on/off.
