C71x: SE returning incorrect data when non-aligned transposed stream crosses AM1 circular buffer boundary

Details:

When AM1 refers to a larger circular buffer size than AM0, SE can reuse the wrong 64B line of data during non-aligned transposed streams. This occurs when one of the rows being transposed crosses the AM1 circular buffer boundary, but not the AM0 boundary.

Workaround(s):

Have the transposed stream either be fully aligned, meaning that the start address and all scaled DIM values be multiples of 64B, or to not configure AM1 to be a larger circular addressing buffers size than AM0.
