ramips: add Xiaomi RA75 red signal led

Browse Source 
RA75 has 5 physical LEDs under 2 indicators, mixed with light pipes:
Indicator "System":
  GPIO0: blue
  GPIO2: amber
Indicator "Signal":
  GPIO44: blue
  GPIO37: amber
  GPIO46: red

All except GPIO46 were already added by Jo Deisenhofer. GPIO46 is used for UART1 by
default, so it needs additional pin control change in devicetree to be operational.
Verified on my RA75.
