os/arch/arm/src/imxrt/chip/imxrt102x_dmamux : Rename duplicate macro
IMXRT_DMACHAN_ACMP3 is duplicated because there is typo in imxrt102x_dmamux.h
So I changed the typo to fit its original purpose
#define IMXRT_DMACHAN_ADC_ETC 23 /* ADC ETC DMA */
#define IMXRT_DMACHAN_ADC1 24 /* ADC1 DMA */
#define IMXRT_DMACHAN_ACMP1 25 /* ACMP1 DMA */
-#define IMXRT_DMACHAN_ACMP3 26 /* ACMP2 DMA */
+#define IMXRT_DMACHAN_ACMP2 26 /* ACMP2 DMA */
#define IMXRT_DMACHAN_FLEXSPI_RX 28 /* FlexSPI RX FIFO DMA */
#define IMXRT_DMACHAN_FLEXSPI_TX 29 /* FlexSPI TX FIFO DMA */
#define IMXRT_DMACHAN_XBAR1_0 30 /* XBAR1 DMA 0 */
