Subject: [PATCH] dt-bindings: pinctrl: k3: Introduce debounce select mux macros

Introduce the debounce select mux macros to allow folks to setup
debounce configuration for pins. Each configuration selected maps
to a specific timing register as documented in appropriate Technical
Reference Manual (example:[1]).
