1. fmu-v6x: Increase Mavlink UART buffers …

   Our serial_test showed only ~84kB/s with the default 256 RX buffer size
   with significant ~2.5ms periods of the flow control RTS pin being
   asserted. Increasing size to 600 (same as FMU-v5x) brings the throughput
   only to ~190kB/s, while a size of >1500 achieves ~350kB/s. Larger RX
   buffers do not increase throughput anymore, while the theoretical
   maximum is 375kB/s.
   
   Transmit buffer size is increased to 10kB same as on FMUv5x to prevent
   any future differences in queue behavior and throughput. serial_test
   showed ~350kB/s throughput at 3kB TX buffer size, so this is just a
   precaution.
