Like for 5/6, why is this function needed? When booting from NAND, the boot ROM
sets the NAND pads appropriately itself (see 7.5.2.4), so unless it reverts
those changes to the IOMUX reset values afterwards, there is no need to set the
NAND IOMUX again. It's not as if the board were using NAND after having been
booted from another source (like mx53ard does).

Or perhaps you are planning to add more boot sources later, in which case there
are configs missing for M4IF and WEIM (see mx53ard's setup_iomux_nand()).
