This commit changes the Arduino Zero pinmux configuration to use PA12 as MISO. According to the schematic, the Arduino Zero provides a SPI bus on SERCOM4 with the following pads/pins: - MISO: PA12/pad0 (pin 21) - MOSI: PB10/pad2 (pin 19) - SCK: PB11/pad3 (pin 20) The MISO signal is incorrectly labeled as PB12_S4_SPI_MISO on the schematic. It should be labeled PA12_S4_SPI_MISO. Signed-off-by: Henrik Brix Andersen <henrik@brixandersen.dk>
