[PATCH v2 8/9] xhci: change xhci 1.0 only restrictions to support xhci 1.1

[Mathias Nyman <mathias.nyman@linux.intel.com>]

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
