There is no symbol 'SOC_IMX6'. Instead, it's 'SOC_IMX6Q'.

It seems that the driver only gets probed in non-dt way. But imx6q
only supports DT. How does this driver work on imx6q?
PS. The regulator DT binding has been available on -next, so I do not
understand why you are still getting regulator_init_data from
platform_data rather than device tree.
