3.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
commit 1a88f809ccb5db1509a7514b187c00b3a995fc82 upstream.
The mvebu-devbus driver had a serious bug, which lead to a 8 bits bus width declared in the Device Tree being considered as a 16 bits bus width when configuring the hardware.
This bug in mvebu-devbus driver was compensated by a symetric mistake in the Armada XP GP Device Tree: a 8 bits bus width was declared, even though the hardware actually has a 16 bits bus width connection with the NOR flash.
Now that we have fixed the mvebu-devbus driver to behave according to its Device Tree binding, this commit fixes the problematic Device Tree files as well.
This bug was introduced in commit da8d1b38356853c37116f9afa29f15648d7fb159 ('ARM: mvebu: Add support for NOR flash device on Armada XP-GP board') which was merged in v3.10.
