[RESEND PATCH v3 1/4] usb: dbc: early driver for xhci debug capability

xHCI debug capability (DbC) is an optional but standalone functionality provided by an xHCI host controller. Software learns this capability by walking through the extended capability list of the host. xHCI specification describes DbC in section 7.6. This patch introduces the code to probe and
