ARM: uniphier: drop code for old DT binding
Commit 307d40c56b0c ("ARM: uniphier: rework SMP code to support new System Bus binding") added a new DT binding for SMP code, but still kept old code for the backward compatibility. Linux 4.6 was out with both bindings supported, so it should not hurt to drop the old code now. Moreover, the mainline code are currently not used for any of our products, so this change has no impact on our customers in any way.
