usb: xhci-mtk: use @tt_info to check the FS/LS device is under a HS hub

Browse Source 
If the LS/FS device is connected to an external HS hub, the member
@tt_info in xhci_virt_device struct in not NULL, use it to check
whether a LS/FS device is under an exernal HS hub, then no need get
the slot context of this device.
