expose UART4 on wioterminal board

Browse Source 
The right-hand grove port on the wioterminal can be used as UART, using
D0/D1 pins.  The pins D0/D1 are tied to SERCOM4, so this patch exposes a
UART4 for sercom4 access.

  RX = A0/D0 = PB08/SERCOM4.0 (port 4 pad 0)
  TX = A1/D1 = PB09/SERCOM4.1 (port 4 pad 1)

Tested with Lora E5 UART.

  uart : = machine.UART4
  tx := machine.D0
  rx := machine.D1

Note: must also cross Tx/Rx wires in grove cable.  See
