ata: add platform driver for Calxeda AHCI controller
Calxeda highbank SATA phy has intermittent problems bringing up a link with Gen3 drives. Retrying the phy hard reset can work-around this issue, but each reset also disables spread spectrum support. The reset function also needs to reprogram the phy to enable spread spectrum support. Create a new driver based on ahci_platform to support the Calxeda Highbank SATA controller.
