The SDHI node needs two kinds of pinmux settings, one for normal speeds
and one for highspeeds. They might differ in supplied voltage, i.e. 3v3
and 1v8. This eMMC always works with 1v8, so both settings needed by the
SDHI node

The eMMC card has two supplies, VCC and VCCQ. The VCC supplies the NAND
array and the VCCQ supplies the bus. On this particular board, the VCC is
connected to 3.3V rail, while the VCCQ is connected to 1.8V rail. Adjust
the pinmux to match the bus, which is always operating in 1.8V mode.
