can you take a look at this patch? It will not cause any regression since we
do not have audio support mainline and the pending serie

Move the code out from arch/arm/common and merge it inside of the dmaengine
driver.
This change is done with as minimal change to the code as possible to avoid
any possibilities to introducing regression.

We no longer have users for these functions so they can be removed.
Remove also unused enums from the header file.

Instead of relying on indexes pointing to edma private date in the global
pointer array, pass the private data pointer via the public API.

Instead of using defines to specify the size of different arrays and
bitmaps, allocate the memory for them based on the information we get from
the HW itself.
Since these defines are set based on the worst case, there are devices
where they are not valid.

Since the driver stack no longer depends on lookup with id number in a
global array of pointers, the limitation for the number of eDMAs are no
longer needed. We can handle as many eDMAs in legacy and DT boot as we have
memory for them to allocate the needed structures.
