From: Bjorn Andersson bjorn.andersson@linaro.org
commit 566bd8902e7fa20bd412ed753e09e89c1c96939c upstream.
SMSM is not symmetrical, the incoming bits from WCNSS are available at index 6, but the outgoing host id for WCNSS is 3. Further more, upstream references the base of APCS (in contrast to downstream), so the register offset of 8 must be included.
