ata: sata_mv: introduce compatible string "marvell, armada-370-sata"

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.
