arm64: dts: ti: Use local header for pinctrl register values
The DTS uses hardware register values directly in pin controller pin
configuration and not an abstraction of any form.
These definitions were previously put in the bindings header to avoid
code duplication and to provide some context meaning (name), but they
do not fit the purpose of bindings.
Store the constants in a header next to DTS and use them instead of
bindings.
