[ Upstream commit 8fd95da2cfb5046c4bb5a3cdc9eb7963ba8b10dd ]
In the probe, some resources are allocated with dwc3_qcom_of_register_core() or dwc3_qcom_acpi_register_core(). The corresponding resources are already coorectly freed in the error handling path of the probe, but not in the remove function.
Fix it.
