samples: sensor: mcux_acmp: add case support for RT1180-EVK

Browse source 
Use gpio_ad_01_acmp1_in2 as ACMP1_IN2, test case can be captured
in J45-13.

This sample show how to use the NXP MCUX Analog Comparator (ACMP) driver. The

The input voltage for the negative input of the analog comparator is
provided by the ACMP Digital-to-Analog Converter (DAC). The input voltage for
the positive input can be adjusted by turning the on-board potentiometer for
