[ Upstream commit08384e80a7] The Device Tree was using invalid node names for the ACT8600 regulators. To be fair, it is not the original committer's fault, as the documentation did gives invalid names as well. In theory, the fix should have been to modify the driver to accept the alternative names. However, even though the act8865 driver spits warnings, the kernel seemed to work fine with what is currently supported upstream. For that reason, I think it is okay to just update the DTS. I removed the "regulator-name" too, since they really didn't bring any information. The node names are enough.
