The current implementation of the libahci does not allow to use multiple
PHYs. This patch adds the support of multiple PHYs by the libahci while
keeping the old bindings valid for device tree compatibility.

This introduce a new way of defining SATA ports in the device tree, with
one port per sub-node. This as the advantage of allowing a per port
configuration. Because some ports may be accessible but disabled in the
device tree, the port_map mask is computed automatically when using
this.

Patch doesn't apply to libata/for-3.17.  Please refresh.

This patch is base on top of v3.16-rc7, taking in account a patch[1]
introduced after rc1 modifying this same file.
