serial: 8250: 8250_omap: Support native RS485
Recent TI Sitara SoCs such as AM64/AM65 have gained the ability to
automatically assert RTS when data is transmitted, obviating the need
to emulate this functionality in software.
The feature is controlled through new DIR_EN and DIR_POL bits in the
Mode Definition Register 3. For details see page 8783 and 8890 of the
AM65 TRM: https://www.ti.com/lit/ug/spruid7e/spruid7e.pdf
