Added MATEKF411SE_SS2_CH6 variant (#6895)

This moves SS2 from TX2 to Ch6, so that UART 2 remains full, while allowing SS2 support, for things like ESC telemetry.

+## Specification:
+
+* STM32F411 CPU
+* OSD
+* BMP280 barometer
+* Integrated PDB for 2 motors
+* 2 UART ports
+* 6 servos
+* no SD card slot
+* 3 BECs
+
+## Details
+
+* [Full specification](http://www.mateksys.com/?portfolio=f411-wse)
+* SBUS pad has a built-in inverter and is connected to UART2 RX
+
+## Available TARGETS
+
+* `MATEKF411SE` Stock target. LED control and have SS1 on ST1 pad, SS2 on TX2 pad.
+* `MATEKF411SE_PINIO` Adds USER 2 PINIO support on the LED pad.
+* `MATEKF411SE_FD_SFTSRL1` Adds full duplex SS1 by putting the RX on the LED pad.
+* `MATEKF411SE_SS2_CH6` SS2 moved to Ch6 pad. This keeps UART 2 as a full UART (for example, for use with Crossfire) and SS2 support.
