That is better as the system will be left in the pinmux configuration
handed over from bootloader.

The point being, muxing up pins even when not needed(config switched
off) has no real benefit - in this case albeit, the default mux was
causing a bug.
pinctrl IMHO should be considered as any other resource, if it is not
mandatory for boot, and needed only for a device functionality when
probed, it should done there only.

just my 2 cents.
