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.

Make use of positive status values in the DMA callback to pass
info to the DMA client after a successful DMA operation.
A completed DMA transfer uses the status 0 while a reached
water mark uses the status 1.

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.

Ensures that the documented behavior of the API is met by implementations
through testing. By calling stop on a stopped channel the expectation is no
error occurs and is checked.
Calling start after a channel has been started is difficult to test for
as there is transfer timing involved. A once shot transfer may have
completed and the channel transition to an inactive state by itself by
the time the second start call is performed. This isn't supported by at
least gpdma today and isn't documented behaviorally so should not be
tested.

As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>.
This patch proposes to then include <zephyr/kernel.h> instead of
<zephyr/zephyr.h> since it is more clear that you are including the
Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a
catch-all header that may be confusing. Most applications need to
include a bunch of other things to compile, e.g. driver headers or
subsystem headers like BT, logging, etc.
The idea of a catch-all header in Zephyr is probably not feasible
anyway. Reason is that Zephyr is not a library, like it could be for
example `libpython`. Zephyr provides many utilities nowadays: a kernel,
drivers, subsystems, etc and things will likely grow. A catch-all header
would be massive, difficult to keep up-to-date. It is also likely that
an application will only build a small subset. Note that subsystem-level
headers may use a catch-all approach to make things easier, though.
NOTE: This patch is **NOT** removing the header, just removing its usage
in-tree. I'd advocate for its deprecation (add a #warning on it), but I
understand many people will have concerns.

Make the test data larger to help slow down the transfer long enough
to get suspend to work. Then attempt to spin on suspend. Suspending any
of the test transfers is a success.
Previous suspend resume test would always fail on DesignWare DMA
as it was seemingly already done by the time dma_suspend would be
called in the ISR.

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.
