[U-Boot] [PATCH v1] dm: pinctrl: Remove obsolete function pinctrl_decode_pin_config_dm().

[Christoph Muellner]

This reverts commit 5ff776889212c080e3d1a33634ac904405ed6845.

As noted in the comment, the function pinctrl_decode_pin_config_dm()
only served as a temporary solution.

Since the function has no users anymore, we can remove it again.
