Stephanos Ioannidis 547a5e9eb0 tests: uart_async_api: Support atsamr21_xpro board ... This commit adds the asynchronous UART API testing support on the SAM R21 Xplained Pro board. The SERCOM3 module is used as the secondary loop-back UART, which is required to run this test. Note that no external UART loop-back connection is necessary to run this test, because the SERCOM3 UART TX and RX pads are configured to be internally connected; it is, however, still necessary to configure the pinmux because the module pads are not connected until the pinmux is configured.
