These are not some IDs or other abstraction layer but raw numbers used in the registers These constants do not fit the purpose of bindings. They do not provide any abstraction, any hardware and driver independent ID. With minor exceptions, the Linux drivers actually do not use the bindings header at all. All of the constants were moved already to headers local to DTS (residing in DTS directory) and to Samsung pinctrl driver (where applicable), so remove any references to the bindings header and add a warning tha tit is deprecated.
