ARM: dts: imx6ul-kontron-bl-common: Fix RTS polarity for RS485 interface

Browse Source 
[ Upstream commit 47ef5256124fb939d8157b13ca048c902435cf23 ]

The polarity of the DE signal of the transceiver is active-high for
sending. Therefore rs485-rts-active-low is wrong and needs to be
removed to make RS485 transmissions work.
