usb: host: xhci-plat: Iterate over parent nodes for finding quirks
In xhci_plat_probe() both sysdev and pdev->dev are being used for finding quirks. There are some drivers(like dwc3 host.c) which adds quirks(like usb3-lpm-capable) into pdev and the logic present in xhci_plat_probe() checks for quirks in either sysdev or pdev for finding the quirks. Because of this logic, some of the quirks are getting missed(usb3-lpm-capable quirk added by dwc3 host.c driver is getting missed).This patch fixes this by iterating over all the available parents for finding the quirks. In this way all the quirks which are present in child or parent are correctly updated.
