USB: dwc3: qcom: fix resource leaks on probe deferral
The driver needs to deregister and free the newly allocated dwc3 core
platform device on ACPI probe errors (e.g. probe deferral) and on driver
unbind but instead it leaked those resources while erroneously dropping
a reference to the parent platform device which is still in use.
For OF probing the driver takes a reference to the dwc3 core platform
device which has also always been leaked.
Fix the broken ACPI tear down and make sure to drop the dwc3 core
reference for both OF and ACPI.

Fixes: 2bc02355f8ba ("usb: dwc3: qcom: Add support for booting with ACPI")
