These GPIOs are exported to the expansion pin header at the rear of the
board:
EXP1_GPIO7: row 1, pin 9 from left
EXP1_GPIO6: row 1, pin 8 from left
Experimentally I could only see EXP1_GPIO6 (the pin currently assigned
to the DSPI driver) actually toggle on an analyzer - I don't know why,
but on my board, EXP1_GPIO7 isn't.
