pin_mux_spi() and pin_mux_usb() are both called from
board/nvidia/common/board.c right before the relevant drivers are
initialized. I think we should centralize the NAND pinmux initialization
there too if possible. That way, when we read the whole pinmux from DT
in the future, there's only one place to go and clean up.

Admittedly, pin_mux_mmc() ends up being called from board_init_mmc()
which is a little unfortunate:-(
