Subject: [PATCH 3/6] ARM: dts: sunxi: h3/h5: Drop A31 fallback compatible for CSI controller

The CSI controller found on the H3 (and H5) is a reduced version of the
one found on the A31. It only has 1 channel, instead of 4 channels for
time-multiplexed BT.656. Since the H3 is a reduced version, it cannot
"fallback" to a compatible that implements more features than it
supports.

Drop the A31 fallback compatible.
