Subject: [PATCH] MIPS: Octeon: Fix fall through on bar type
 OCTEON_DMA_BAR_TYPE_SMALL

Bar type OCTEON_DMA_BAR_TYPE_SMALL assigns lo and hi addresses and
then falls through to OCTEON_DMA_BAR_TYPE_BIG that re-assignes lo and
hi addresses with totally different values. Add a break so we don't
fall through.
