Subject: [PATCH v4 0/3] USB: dwc:  Add workaround for host mode VBUS glitch when boot

Chagne from v2 to v3
- see notes at patch

Change from v1 to v2:
- splite xhci.h to xchi-port.h and xhci-caps.h to shared marco.
- add quirk subfix
- fixed checkpatch error with --strict.

left one warning to align existed code style.

CHECK: Alignment should match open parenthesis
+	dwc->host_vbus_glitches_quirk = device_property_read_bool(dev,
+				"snps,host-vbus-glitches-quirk");
