SDOCM00113029: Fix issue with limited size of EdmaMgr's internal heap.
While the memory requirements for regular EdmaMgr channels are constrained
relative to HW resources, large channels may require arbitrarily large memory for
the lookup tables used in the chained transfers. Therefore this memory must come
from outside EdmaMgr. The function EdmaMgr_getSizesLarge is introduced to provide
the application with the buffer requirements for a large channel based on a
supplied configuration.
