Subject: [PATCH] dt-bindings: pinctrl: samsung: drop unused header with register constants

The bindings header for Samsung pin controller DTS pin values (holding
register values in fact) was deprecated in v6.1 kernel in
commit 9d9292576810 ("dt-bindings: pinctrl: samsung: deprecate header
with register constants").  This was enough of time for users to switch
to in-DTS headers, so drop the bindings header.
