tests: dma loop_transfer: Ex of LPC DMA Kconfig
Show an example of the LPC DMA Kconfig to reduce RAM based on the number of DMA channels expected to be used. In this test, only one DMA channel is needed, so we can show an example of how to reduce RAM usage of the driver by configuring this value appropriately.
