usb: xhci: simplify TDs start and end naming scheme in struct 'xhci_td'
Old names:
* start_seg - last_trb_seg
* first_trb - last_trb
New names:
* start_seg - end_seg
* start_trb - end_trb
A Transfer Descriptor (TD) in the xhci driver is a data structure that
represents a single transaction to be performed by the USB host controller.
This transaction is defined by TRBs from 'start_trb' in 'start_seg' to
'end_trb' in 'end_seg'.
The terms "start" and "end" were chosen over "first" and "last" for ease
of searching within the codebase. The ring structure uses 'first_seg' and
'last_seg', while the TD structure uses 'start_seg' and 'end_seg'.
