This series adds support for SATA using the driver model on omap platforms.
It is based on the work of Mugunthan V N <mugunthanvnm at ti.com> in Feb 2016
In the process it adds a new framework to manage PHY devices

changes since v4:
- added some revievewed-by tags
- fixed some nits (ordering, blank lines, ...)

changes since v3:
* Add a patch to split scsi_scan() as discussed in https://patchwork.ozlabs.org/patch/748210/
* reworked the PHY framework to support multiple port PHY devices (required to
  be compatible with the device-tree bindings used in linux). Updated the tests
  as well.
* moved away from "generic[_-]phy" to simply use 'phy' instead. Expect for the name
  of the header file 'generic-phy.h' and for the names of the functions of the API,
  because it's already used by the Ethernet PHY code.
* rebased on top of u-boot-dm/master
* removed the patches already taken in u-boot-dm/master

changes since v2:
* Added unit tests for generic PHY uclass.
* Changed the generic phy API to use a 'struct udevice*' to reference the phy
  device.
* Don't modify anymore the root Makefile.
* Updated the Kconfig with more details on the PHY framework.
* Use a Unique Lincense Identifier (SPDX)
* Use omap5-u-boot.dtsi to mark the ocp2scp bus as compatible with "simple-bus"
* Split scsi_scan() in 2 for clarity. The function was becoming too long.

changes since v1:
* changed the way the 'old' sata code is compiled out when DM_SCSI is enabled.
* added a new framework for PHY management.
* added a new driver for the PIPE3 phy and use it in the dwc_ahci driver.
* changed the interface of scsi_detect_dev() and moved the call part_init() out
  of it.
* modified the fix to scsi_scan() in order to call scsi_detect_dev() only once.
* the max_lun and max_id parameters are now taken from the device-tree.
* Updated the defconfig changes to include the PHY driver and its dependencies.
