[PATCH 12/16] cpuidle: mvebu: Rename the driver from armada-370-xp to mvebu-v7

Gregory CLEMENT
2014-06-27T13:24:03Z

Actually this driver will be able to manage the cpuidle for more SoCs
that Armada 370 ad XP. It will support Armada 38x and potentially
Armada 375. This patch change the names accordingly to this behavior.
