The value is 4, it can cache four descriptors. When streaming_interval = 1,
it can tolerate 500us. Some busy scenes, it may be more than 500us because
cpu scheduling is not timely. There will have some problems. It is better

In removal requests, it is necessary to make the corresponding trb
disable state (HWO = 1) and dep->queued_requests a corresponding reduction.
It is better to use a alone funtion to disable trb (HWO = 0).

Iso transmission, the current process is that all trb(HWO=1) is handled.
Then core generate DWC3_DEPEVT_XFERNOTREADY event, Software begin refill
trb, this will produce 0 length package, the patch is to achieve the core
consumes a trb, and then the software fill a trb. Normally, there will never
