imx6, aristainetos2c: add da9063 pmic setup

Browse Source 
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.
