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.
