atmel-samd: Add SAM E54 Xplained board
Few peripherals are actually tested. However, USB, I2C and GPIO seem to work. Most pins are silkscreened with the "PX00" style, so the board module only includes the small number that are screened differently. The default SPI, I2C, and UART are the ones on the EXT2 header. This is arbitrary, but the I2C on this connector is shared with the on-board I2C devices and the PCC header, making it the most versatile.
