Add a helper function to be able to set the maximum
VPDMA transfer size to limit potential buffer overrun.

Added enums for max_width and max_height fields of the
outbound data descriptor.

Changed vpdma_add_out_dtd to accept two more arguments
for max width and height.

Make use of different max width & height sets for different
of capture module (i.e. slices).
