Log:
 - Call acpi_bus_set_power instead of acpi_power_transition
 - Make sure the device has power management capabilities before calling
acpi_bus_set_power
 - Report the new power state with PoSetPowerState
 - Initialize PDOs with the correct device power state (Patch by Samuel Serapion)
 - Initialze PDOs with the correct system power state
