tty: serial: sh-sci: Fix TE setting on SCI IP
As per the RZ/G2L users hardware manual (Rev.1.20 Sep, 2022), section
23.3.7 Serial Data Transmission (Asynchronous Mode) it is mentioned
that the TE (transmit enable) must be set after setting TIE (transmit
interrupt enable) or these 2 bits are set to 1 simultaneously by a
single instruction. So set these 2 bits in single instruction.
