Leverages the configuration generated by the TI recommended PinMux
utility to enable pins for the 4 GPIO ports on the CC32xx LaunchXL
board, pre-configuring GPIOs for the onboard:
- 3 LEDs, and
- Two user push buttons (SW2, SW3).
The pinmux configuration is used in lieu of a Zephyr
pinmux driver, and is called during board initialization.
