PM8916 definitely has USB_IN pads (pad # N13, P13). 😄

Let me check again.

No sorry USB_IN_0 and USB_IN_1 are connected to +5V in my schematic, I did check USB_IN I just forgot why it wasn't usable... +5v not VBUS is what its connected to.

VBUS connects to VBUS_DET on the USB Hub - a USB2514BQFN36, there's no corresponding routing of VBUS onto a GPIO or USB_IN_x on the PMIC.

I assume there's some good reason the PCB designer did it this way .. there's enough of a reason behind it that Qcom put a workaround for the case where PCBs don't route the VBUS state to the SoC or PMIC.
