BTW it is possible now to put the U-Boot-specific changes that you
can't get upstream in a separate file with a -u-boot.dtsi suffix. See
'Automatic .dtsi inclusion' in the binman README.

Also with your move of the pio nodes to be siblings, you should be
able to make the GPIO a child of the pinctrl driver by having
something like:

        .post_bind      = dm_scan_fdt_dev,

in your pinctrl driver.
