> Registers HW_PINCTRL_DRIVE9, HW_PINCTRL_DRIVE10, HW_PINCTRL_DRIVE11,
> HW_PINCTRL_DRIVE12, HW_PINCTRL_DRIVE13 and HW_PINCTRL_DRIVE14 control the
> drive strength and the voltage selection for the DDR pins.
>
> The reset values of the voltage selection pins are '1', which is marked as
> 'reserved' in the mx23 reference manual.
>
> Clear these bits for proper operation of DDR.

> Also change MUX_CONFIG_EMI, which results in better stability and match the
