Asus F2A85-M: Fix S3 memory power cut-off
The power to memory is lost during the the suspend, activate the 3VSBSW# which switches the power during S3 suspend sequence.
As a result resuming from suspend to RAM works now, but now the GPP ports of the Hudson southbridge are gone after resume from S3. The devices 15.0 and 15.1 are disabled (decode as ffff) and therefore anything behind them too [1].
