Set the controller speed to HCD_USB31 to if host hardware supports USB 3.1
For PCI xhci controllers the USB 3.1 support is checked from SBRN bits in
pci config space. Platform controllers will need to set xhci->sbrn == 0x31
to indicate USB 3.1 support before calling xhci_gen_setup().
Also make sure xhci driver works correctly with speed set to HCD_USB31

If the xhci controller supports USB 3.1 enhanced SuperSpeed, meaning

This also gave me a warning with the assignment:
visorinput_dev->keycode = visorkbd_keycode;
because input_dev->keycode is NOT static but visorkbd_keycode now is, so
I went ahead and also added logic to stash away non-static copies of
visorkbd_keycode[] and visorkbd_ext_keycode[] within visorinput_devdata,
and use the copy to assign to visorinput_dev->keycode. This change is
also technically required, because user-space can remap keys, and we
don't want this to be shared with the other keyboard devices running on
the same system.

In order to be more consistent with kernel conventions used elsewhere,
I have re-ordered declarations in visorinput.c to follow this general
order (where possible):
* #defines
* struct/enum/union declarations
* static declarations (const if possible for all of them)
* forward function declarations where absolutely necessary
Exceptions were made for the static declarations like the driver
declaration, given that it depends on previously-defined callbacks.
So such declarations are at the end of visorinput.c.
