xhci: Fix resume issue of some ZHAOXIN hosts
commit f927728186f0de1167262d6a632f9f7e96433d1a upstream.
On ZHAOXIN ZX-100 project, xHCI can't work normally after resume
from system Sx state. To fix this issue, when resume from system
Sx state, reinitialize xHCI instead of restore.
So, Add XHCI_RESET_ON_RESUME quirk for ZX-100 to fix issue of
resuming from system Sx state.
