[PATCH v2 07/10] ARM: dts: qcom: msm8960: add SMEM & hwlock

[Antony Kurniawan Soemardi via B4 Relay]

From: Antony Kurniawan Soemardi <linux@xxxxxxxxxxxxxx>

Enable shared memory communication and add the SFPB lock for MSM8960.
These provide the foundation for inter-processor communication with the
Riva (BT + Wi-Fi) subsystem.
