ata: add AMD Seattle platform driver
AMD Seattle SATA controller mostly conforms to AHCI interface with some special register to control SGPIO interface. In the case of an AHCI controller, the SGPIO feature is ideally implemented using the "Enclosure Management" register of the AHCI controller, but those registeres are not implemented in the Seattle SoC. Instead SoC (Rev B0 onwards) provides a 32-bit SGPIO control register which should be programmed to control the activity, locate and fault LEDs. The driver is based on ahci_platform driver.
