This series is for supporting typical full speed USB audio headsets
with speaker, microphone, and control knobs together.
With current implementation, such a device cannot be configured
due to xhci-mtk's bandwidth allocation failure even when there's
enough bandwidth available.

2.31.0.291.g576ba9dcdaf-goog
Software bandwidth checking logics used by xhci-mtk puts
a quite heavy constraints to TT periodic endpoint allocations.
This patch provides a relaxed bandwidth calculation by
- Allowing multiple periodic transactions in a same microframe
for a device with multiple interrupt endpoints.
- Using best case budget instead of maximum number of
complete-split when calculating byte budgets on lower speed bus
Without this patch, a typical full speed audio headset with
3 periodic endpoints (audio isoc-in/out, input int-in) cannot be
configured with xhci-mtk.
