arm64: dts: imx8mp-kontron: Fix CAN_ADDR0 and CAN_ADDR1 GPIOs

Some signal assignments were modified between hardware revisions
1 and 2:

Revision 1:

  - SPI_A_WP   -> CAN_ADDR0
  - SPI_A_HOLD -> CAN_ADDR1

Revision 2 and later:

  - SPI_A_SDI -> CAN_ADDR0
  - SPI_A_SDO -> CAN_ADDR1

Fix the labels and add the missing pinctrls.
