[PATCH] Fix QUICC Engine SDMA setup errors

Correct the alignment of the internal buffer used by the QUICC Engine
SDMA controller to 4Kbytes.  Correct the shift direction in the logic
that sets up the SDMR register for the QUICC Engine SDMA controller.

In addition to fixing the bugs, this version of this patch addresses
Segher's concerns about fixing the line break placement.  It also
addresses Leo's concerns about using the more accurate term
"QUICC Engine" rather than "MPC83xx" in the subject and header.
