xhci: make isoc_bei_interval variable interrupter specific.
isoc_bei_interval is used to balance how often completed isochronous
events cause interrupts. If interval is too large then the event ring
may fill up before the completed isoc TRBs are handled.
isoc_bei_interval is tuned based on how full the event ring is.
isoc_bei_interval variable needs to be per interrupter as
with several interrupters each one has its own event ring.
move isoc_bei_interval variable to the interrupter structure.
if a secondary interrupter does not care about this feature then
keep isoc_bei_interval 0.
