Asus F2A85-M: Move to ther proper SIO 

The F2A85-M has IT8603E which is a strip down version of IT8728F.
Change configuration from provisional IT8712F to the IT8728F.
While at it also enable only needed LPC bridge decodes.
As the side effect, this change also implements setup of environmental
controller, thus it87 driver can detect the temperatures/fans.
