ahci-imx: Port to library-ised ahci_platform
This avoids the ugliness of creating a nested platform device from probe. While moving it around anyways, move the mk6q phy init code from probe to imx_sata_enable, as the phy needs to be re-initialized on resume too, otherwise the drive won't be recognized after resume. Tested on a wandboard i.mx6 quad. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Tejun Heo <tj@kernel.org>
