Subject: [PATCH v5 10/10] interconnect: qcom: msm8996: Promote to
 core_initcall

The interconnect driver is (or soon will be) vital to many other
devices, as it's not a given that the bootloader will set up enough
bandwidth for us or that the values we come into are reasonable.

Promote the driver to core_initcall to ensure the consumers (i.e.
most "meaningful" parts of the SoC) can probe without deferrals.
