For NXP SoCs we have to set pinmux configuration ASAP (ideally
before relocation) to get serial console working. Without this we miss
almost the half of output (U-boot version, CPU defails, Reset cause,
DRAM details etc.).
To achieve this we need to force appropriate pinctrl drivers to get
probed before relocation.
Fixes: cd69e8ef9b ("colibri-imx6ull: migrate pinctrl and regulators to dtb/dm")
