serial/sc16is7xx: Remove obsolete #ifset TIOC[SG]RS485
serial/sc16is7xx: Remove obsolete #ifset TIOC[SG]RS485

Commit e676253b19b2 ("serial/8250: Add support for RS485 IOCTLs") added
references to TIOC[SG]RS48 on 8250_core.c. This change triggered the
need to define them in all the arches that uses tty/serial.

This made #ifdef TIOC[SG]RS48 obsolete.
