Custom SAMD51 Board (Add pins in variant files) Issue

Hi S1buell,

Port pins PB00 and PB01 are on ADC0/AIN[12] and ADC0/AIN[13] respectively. This information is taken from the SAMD51 Datasheet's "I/O Multiplexing and Considerations" table.

Therefore it should be possible to set up an analog pin for PB00:

{ PORTB, 0, PIO_ANALOG, PIN_ATTR_ANALOG, ADC_Channel12, NOT_ON_PWM, NOT_ON_TIMER, EXTERNAL_INT_0 }, // ADC0/AIN[12]

and for PB01:

{ PORTB, 1, PIO_ANALOG, PIN_ATTR_ANALOG, ADC_Channel13, NOT_ON_PWM, NOT_ON_TIMER, EXTERNAL_INT_1 }, // ADC0/AIN[13]
