drivers/usb: Skip auto handoff for TI and RENESAS usb controllers

I have never seen auto handoff working on TI and RENESAS xhci
cards. Eventually, we force handoff. This code forces the handoff
unconditionally. It saves 5 seconds boot time for each card.
Added the vendor/device id checks for the card which I have tested.
