drivers/usb/dwc3: fix PCI parent check

The sysdev_is_parent check was being used to infer PCI devices that have
the DMA mask set from the PCI capabilities, but sysdev_is_parent is also
used for non-PCI ACPI devices in which case the DMA mask would be the
bus default or as set by the _DMA method.

Without this fix the DMA mask would default to 32-bits and so allocation
would fail if there was no DRAM below 4GB.
