Add DMA unit tests for BDMA driver.
Also requires adding additional kconfig options to allocate
the memory buffers in a specific SRAM section, because
the BDMA only has access to SRAM4.

Convert test to use DEVICE_DT_GET via a nodelabel.
Introduce a test_dma devicetree nodelabel to reference the DMA
controller the test should use.

Add Kconfig with the following options:
- DMA_LOOP_TRANSFER_DRV_NAME to set the DMA device name, because
some SOCs do not allow memory to memory DMA on all DMA devices
- DMA_LOOP_TRANSFER_CHANNEL_NR some SOCs start counting the DMA
channels at 1 instead of 0.
