arm64: dts: Enable onboard SDHCI on msm8992
This enables SDHCI on the Nexus 5X as well creates common smd_rpm node which can be shared between both 5X and 6P as per HW design. Given the lack of documentation, only downstream code was used as a reference and it eludes to the fact that 8994-rpm-regulator is common between both msm8992 & msm8994. [ see msm.git branch: msm-angler-3.10-marshmallow-mr1, msm8992.dtsi] At this early stage of development it makes sense for the 8994-rpm-regulator to be common until data / documentation suggests otherwise.
