boards: frdm_mcxn236: Change lpuart0 pin configuration

PR https://github.com/zephyrproject-rtos/zephyr/pull/96980/
changed the pins of lpuart0 from 'FC0_P0_PIO0_16' and
'FC0_P1_PIO0_17' to 'FC0_P2_PIO0_6' and 'FC0_P3_PIO0_7'.
This is actually unnecessary because lpuart0 is not enabled
by default, so micfil applications will not be affected.
Even if lpuart0 were enabled by default, we should disable
lpuart0 at the application layer rather than directly
modifying its default configuration, as this behavior lacks
backward compatibility.
