drivers: char: mem: Simplify DEVPORT configuration
Simplify the use of CONFIG_DEVPORT by making the port_fops so that it includes __maybe_unused. This enabled the multiple #ifdef's used for this structure to be removed and brings it in line with the use of CONFIG_DEVMEM This change should introduce no functional changes.
