Eliminates dma tests' dependency on CONFIG_NOCACHE_MEMORY=y for
configuring dma data linker sections. This allows optionally relocating
dma source and destination data to sram or other custom linker section
on boards that don't support dma access to flash.

Each SoC may have different limitation regarding DMA buffer size.
This commit places the test transfer size in Kconfig so it can
be modified accordingly.

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.
