I'd split this series into different logical parts:

patch 1/4
   Set XHCI_RESET_ON_RESUME quirk to ZHAOXIN host to fix resume issue.
   cc: stable

patch 2/4
   Add XHCI_ZHAOXIN_TRB_FETCH quirk flag together with code that allocates double pages
   cc: stable

patch 3/4
   Add XHCI_ZHAOXIN_HOST quirk flag together with code that corrects USB3 roothub minor version
   cc: stable

patch 4/4
   Set XHCI_LPM_SUPPORT quirk together with code that sets tier policy and u1/u2 timeouts,
   Don't add stable as this is about adding feature support.

(Accidentally replied to older v2 series with the above comments)
