xhci: sort out TRB Endpoint ID bitfield macros

xhci macros that read and write endpoint ID bitfields of TRBs are mixing
the 1-based Endpoint ID as described in the xHCI specification, and
0-based endpoint index used by driver as an array index.

Sort this out by naming macros that deal with 1 based Endpoint ID fields
to *_EP_ID_*, and 0 based endpoint index values to *_EP_INDEX_*.
