Subject: [PATCH v1] dt-bindings: serial: 8250_omap: add rs485-rts-active-high

From: Francesco Dolcini <francesco.dolcini@...adex.com>

Add rs485-rts-active-high property, this was removed by mistake.
In general we just use rs485-rts-active-low property, however the OMAP
UART for legacy reason uses the -high one.

Fixes: 767d3467eb60 ("dt-bindings: serial: 8250_omap: drop rs485 properties")
Reported-by: Francesco Dolcini <francesco.dolcini@...adex.com>
Closes: https://lore.kernel.org/all/ZGefR4mTHHo1iQ7H@francesco-nb.int.toradex.com/
