Subject: [PATCH linux-next] MIPS: ioctls: Add missing TIOC{S,G}RS485 definitions

Commit e676253b19b2d269cccf67fdb1592120a0cd0676
(serial/8250: Add support for RS485 IOCTLs) added cases for the
TIOC{S,G}RS485 commands but this broke the build for MIPS:

drivers/tty/serial/8250/8250_core.c: In function 'serial8250_ioctl':
drivers/tty/serial/8250/8250_core.c:2874:7: error: 'TIOCSRS485' undeclared
(first use in this function)
drivers/tty/serial/8250/8250_core.c:2886:7: error: 'TIOCGRS485' undeclared
(first use in this function)

This patch adds these missing definitions
