xhci: change xhci 1.0 only restrictions to support xhci 1.1 

commit dca7794539eff04b786fb6907186989e5eaaa9c2 upstream.

Some changes between xhci 0.96 and xhci 1.0 specifications forced us to
check the hci version in code, some of these checks were implemented as
hci_version == 1.0, which will not work with new xhci 1.1 controllers.

xhci 1.1 behaves similar to xhci 1.0 in these cases, so change these
checks to hci_version >= 1.0
