Subject: [PATCH 0/2] arm64: dts: qcom: msm8996: fix issues with probing of
 USB hosts

The lack of the interconnects for the USB2 host might result in the
register writes for the PHY not reaching the PHY and thus the PLL not
locking up, resulting in -EBUSY errors for the USB host on the platform.
Add missing interconnect link and add interconnect paths to the USB2
device.
