serial_core: uart_set_ldisc infrastructure
The tty layer provides a callback that is used when the line discipline is changed. Some hardware uses this to configure hardware specific features such as IrDA mode on serial ports. Unfortunately the serial layer does not provide this feature or pass it down to drivers. Blackfin used to hack around this by rewriting the tty ops, but those are now properly shared and const so the hack fails. Instead provide the proper operations. This change plus a follow up from the Blackfin guys is needed to avoid blackfin losing features in this release.
