xhci: simplify and rework trb_in_td()
The trb_in_td() checking is quite complex, especially when checking for
TRBs in ranges that can span several segments.
Simplify the search by creating a position index for each TRB on the
ring, and just compare the position indexes.
Add a more generic dma_in_range() helper that checks if a trb dma
address is in the range between a start and end trb and call it from
trb_in_td()
