Add new board BDMICRO 'Vina M0'.
ports/atmel-samd/boards/bdmicro_vina_m0/board.c ports/atmel-samd/boards/bdmicro_vina_m0/mpconfigboard.h ports/atmel-samd/boards/bdmicro_vina_m0/mpconfigboard.mk ports/atmel-samd/boards/bdmicro_vina_m0/board.c This board includes the newly added MX25L51245G 64MB SPI flash chip for the CircuitPython file system. Also included is the PCF2129T/2,518 high accuracy, battery backed, RTC. Also includes an independent USB HOST connector in addition to USB DEVICE making it easy to connect USB peripherals. Designed mainly as a general purpose module to piggy back onto application-specific boards, it can also run low power standalone in harsh environments for data logging and other control applications using an appropriate enclosure. Has been extensively tested with CircuitPython and works well.
