Since the CPU port 4 of the switch is hardwired inside the SoC to go to
the enetc port 2, this shouldn't be something that the board files need
to set (but whether that CPU port is used or not is another discussion).

So move the DSA "ethernet" property to the common dtsi.

that works on all operating points and all LPDDR4 types used on the

devicetree to make sure it isn't used.

It turns out that it is not necessary to declare the VSELECT signal as
GPIO and let the PMIC driver set it to a fixed high level. This switches
the voltage between 3.3V and 1.8V by setting the PMIC register for LDO5
accordingly.

Instead we can do it like other boards already do and simply mux the
VSELECT signal of the USDHC interface to the pin. This makes sure that
the correct voltage is selected by setting the PMIC's SD_VSEL input
to high or low accordingly.
