arm64: dts: qcom: msm8916: Add RPM sleep stats

Browse Source 
MSM8916 is similar to the other SoCs that had the RPM stats node added
in commit 290bc68465 ("arm64: dts: qcom: Enable RPM Sleep stats").
However, the dynamic offset readable at 0x14 seems only available on
some of the newer firmware versions. To be absolutely sure, make use
of the new qcom,msm8916-rpm-stats compatible that reads the sleep stats
from a fixed offset of 0xdba0.

Statistics are available for a "vmin" and "xosd" low power mode:

$ cat /sys/kernel/debug/qcom_stats/vmin

$ cat /sys/kernel/debug/qcom_stats/xosd
