Subject: [PATCH 4.9 43/77] arm64: dts: msm8916: Correct ipc references for smsm

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Bjorn Andersson <bjorn.andersson@...aro.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.

Fixes: 1fb47e0a9ba4 ("arm64: dts: qcom: msm8916: Add smsm and smp2p nodes")
