xhci: Add command completion parameter support

xHC hosts can pass 24 bits of data with a command completion event TRB
as the completion code only uses 8 bits of the 32 bit status field.

Only Configure Endpoint, and Get Extended Property commands utilize
this "command completion parameter" 24 bit field.
For other command completion events the xHC should keep it RsvdZ.
