According to the FRDM-MCXA266 user manual, the MCU-LINK VCOM port is connected to LPUART2 instead of LPUART3. Forgot to check that in when #12 was merged in, so this PR updates it. Tested to be working with ec-test-app.

Pull request overview

This PR corrects the dev-mcxa board UART routing so the ODP UART service uses the MCU-LINK VCOM-connected LPUART2 instead of LPUART3.

Changes:

  • Rebinds the LPUART interrupt handler from LPUART3 to LPUART2.
  • Updates UART initialization to use LPUART2 with the corresponding P2_2/P2_3 pins.
