xhci: Add ZHAOXIN xHCI host U1/U2 feature support
Add U1/U2 feature support of xHCI for ZHAOXIN.
Since both INTEL and ZHAOXIN need to check the tier where the device is
located to determine whether to enabled U1/U2, remove the previous INTEL
U1/U2 tier policy and add common policy in xhci_check_tier_policy.
If vendor has specific U1/U2 enable policy,quirks can be add to declare.
