The SD1 pinctrl-0 property is overridden but only the card detect pin
is muxed, the control and data signals are not referenced at all.
It worked because the bootloader muxed them to a sensible state though.

Declared as a regulator since the driver doesn't have a reset-gpios
property for this.

This ensures that the PHY is woken up, not depending on the state the
second stage bootloader leaves the pin.

This is a workaround until a proper mechanism is provided to reset such
devices like the pwrseq library [1] for instance.

The IPU that drives HDMI must have its pre_sel set to pll2_pfd_396m
to avoid stepping on the LVDS output's toes, as the PLL can't be clocked
to the pixel clock and to the LVDS serial clock (3.5*pixel clock) at the
same time.

As we are using ipu1_di0 and ipu2_di0, ensure both are switched to
to pll2_pfd2_396m to avoid issues. The LDB driver will switch the
required IPU to ldb_di1 when it uses it to drive LVDS.
