src/southbridge/amd/sb700: Reset SATA controller in AHCI mode during startup
In AHCI mode SeaBIOS randomly fails to detect disks (AHCI timeouts), with the probability of a failure increasing with the number of disks connected to the controller. Resetting the SATA controller appears to show the true state of the underlying hardware, allowing the drive detection code to attempt link renegotiation as needed.
