Add three I2C GPIO expander devices on the i2c5 bus of the Talos
Lyra EVK carrier board:

  • expander0 (gpio@20): Kinetic KTS1622 16-bit I2C GPIO expander
    (compatible with NXP PCA9555)
  • expander1 (gpio@21): Kinetic KTS1622 16-bit I2C GPIO expander
    (compatible with NXP PCA9555)
  • expander2 (gpio@38): TI TCA9538 8-bit I2C GPIO expander
