ARM: mvebu: fix NOR bus-width in Armada XP OpenBlocks AX3 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 OpenBlocks AX3 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
a7d4f81821f7eec3175f8e23dd6949c71ab2da43 ('ARM: mvebu: Add support for
NOR flash device on Openblocks AX3 board') which was merged in v3.10.
