ARM: mvebu: fix NOR bus-width in Armada XP GP Device Tree
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.
