ata: Add APM X-Gene SoC 6.0Gbps SATA PHY support
This patch adds support for APM X-Gene SoC 6.0Gbps SATA PHY. This is the
physical layer interface for the corresponding SATA host controller. This
driver uses the new PHY generic framework posted by Kishon Vijay Abrahm.
In addition, the new PHY generic framework is patched to provide an
function to set the speed of the PHY.
v2
* Remove port knowledge from functions
* Make all functions static
* Remove ID completely
* Make resource requirement based on compatible type
* Rename override PHY parameters with more descriptive name
* Add override PHY parameter for per controller, per port, and per speed
* Patch the generic PHY frame to expose set_speed operation
v1
* Initial version
