This patch is to optimize xhci_find_realport_number(). Call
xhci_find_raw_port_number() to get real index in the HW port
status registers instead of scanning through the xHCI roothub
port array.

This patch is to bind xhci root hub usb port with its acpi node.
The port num in the acpi table matches with the sequence in the xhci
extended capabilities table. So call usb_hcd_find_raw_port_number() to
transfer hub port num into raw port number which associates with
the sequence in the xhci exte
xhci driver divides the root hub into two logical hubs which work
respectively for usb 2.0 and usb 3.0 devices. They are independent
devices in the usb core. But in the ACPI table, it's one device node
and all usb2.0 and usb3.0 ports are under it. Binding usb port with
its acpi node needs the raw p

The use of memcmp() is clever and all and maybe even it makes parsing a
bit faster (since only options with given length need to be checked) but
option parsing is hardly a critical path and the additional code
complexity is not worth it.
