[PATCH 3.11 135/233] ata: sata_mv: introduce compatible string "marvell, armada-370-sata"

[Luis Henriques]

3.11.10.4 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Simon Guinot <simon.guinot@xxxxxxxxxxxx>

commit b1f5c73bd5a4752efb7d7af019034044b08aafe9 upstream.

The sata_mv driver supports the SATA IP found in several Marvell SoCs.
As some new SATA registers have been introduced with the Armada 370/XP
SoCs, a way to identify them is needed.

This patch introduces a new compatible string for the SATA IP found in
Armada 370/XP SoCs.
