[PATCH] dma: bcm2835: Fix compiler warning on arm64.

The min() macro was complaining about mismatched types.  The max len
is at most SZ_1G, so we can just put it in an unsigned int.

Vinod, if you ack it, this one would be nice to be able to merge
through the -soc tree, so that when we enable of arm64 builds of this
driver we don't introduce a new compiler warning.
