Pinconfig nodes normally bind recursively with PINCTRL_FULL and PINCONF_RECURSIVE enabled. However, during U-Boot proper pre-relocation any node marked with e.g. bootph-all will not bind unless its parent is also marked for pre-reloc.
group1 { pinconf1 { bootph-all; }; };
This cause the following warning message to be shown during U-Boot proper pre-reloc stage on Rockchip RK3568 devices.
ns16550_serial serial@fe660000: pinctrl_select_state_full: uclass_get_device_by_phandle_id: err=-19
Check pinconfig nodes pre-reloc status recursively to fix this and to make pinconfig_post_bind work same at both U-Boot proper pre-reloc and at TPL/SPL stage.

This is actually something we want to change about fdtgrep. I believe we should try to adjust that tool rather than loading this ontoU-Boot, not least because it controls what properties are visible in SPL.
