Brian Dean 3e558a89ac boards/bdmicro_vina_d51: A few updates for flexibility and expansion.
ESP-01 header renamed to AUX, and expanded to 12 pins from 8
pins. Pins 1-8 still accommodate the ESP-01, with expansion to full
SERCOM 4-pad support to allow for SPI and I2C on that expansion port
with additional GPIO control.

Update pins.c with additional signals provided AUX_1-8, along with
UART, SPI, I2C name usage as aliases to appropriate AUX_1-8
signals. Additionally, add several alternate names specific to several
expansion modules - the ESP-01, and the ATW-01 using the WINC_1500
(SPI) w/interrupt and control needed for the WINC - with assignments
to module pin positions.

Re-work SERCOM assignments to accommodate the above from other parts
of the board, which required moving a SERCOM or two around in order to
accommodate the 4-pad sercom pin mapping on the AUX port.

Built and tested using latest from 'main':
