The cpu core is clocked from the "cpu" clock. Add a reference to it in the first cpu node. Also add "cpu0" label to the node. The operating points were taken from the a list compiled by Maxime Ripard, which is based on A31 FEX files from the sunxi-boards repository. Not all boards have the same settings. The settings in this patch are the ones shared by A/B/C revisions, plus the default clock setting from u-boot.
