Config the sram0 to be non-cachable to PASS the DMA testcases
chan_blen_transfer and loop_transfer
on the stm32f746zg and stm32f767zi nucleo boards.
The CONFIG_NOCACHE_MEMORY is useless as the memory region
gets the NOCACHE ATTRibutes for stm32H7 or stm32F7 as well.

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.

Change this test to use the automatically generated linker section
to place the buffer in SRAM4, instead of using the manually created
region added in 088d38f. This is in preperation of removing the
manually created section.

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.
