imx6, aristainetos2c: add da9063 pmic setup

On the aristainetos2c boards the PMIC needs to be initialized, because the Ethernet PHY uses a different regulator that is not setup per hardware default. This does not influence the other versions as this regulator isn't used there at all. Signed-off-by: Heiko Schocher <hs@denx.de>
