That's my plan. But still even if we keep the binding the same, the
actual pinmux config would differ between the kernel and U-Boot (a lot
more pads kept in tristate in U-Boot). So as the FDT would effectively
resemble the same tables I included in this patchset, some testing
coverage of that would smoothen the transition.
