[PATCH v2] ARM: dts: armada-38x: label USB and SATA nodes

Recently most nodes got labels to make them referenceable. The USB 3.0
nodes as well as the nodes for the SATA controllers were left out,
rectify the omission.

The labels "sataX" are already used by some boards for the SATA ports,
therefore use "ahciX" to label the SATA controller nodes.

To avoid potential confusion by labeling an USB3.0 controller "usb2" use
usb3_X as labels. This also coincides with the node names themselves
(usb at xxxxx vs usb3 at xxxxx).

Hi everybody,

Using satacX for controllers with satacXpY for ports might have been a
possiblity, since ahciX is already used similarly (to avoid a conflict
with current use of sataX) ahciX seems the better choice. Works well me
thinks.

The usb3_X labels still seem the best choice even though they aren't
perfectly consitent, however, I don't see an alternative which would fit
this requirement either.

Regards
Ralph

Changes v1 -> v2:
  * use ahciX instead of satacX for the SATA controller nodes (suggested
    by Andrew Lunn)
