Josua Mayer 9dcc0e1065 arm64: dts: ti: k3-am642-hummingboard-t: correct rs485 rts polarity
The RS485 transceiver RE (Receiver enable) and DE (Driver enable) are
shorted and connected to both RTS/CTS of the SoC UART.
RE is active-low, DE is active-high.

Remove the "rs485-rts-active-low" flag to match RTS polarity with DE,
and fix communication in both transmit and receive directions.
