SOP connected indicates a PD contract is in place, and is a solid

To save memory usage, it needs to reduce number of entries in the proc

Some devices have USB compositions which may require multiple endpoints
that support EP bursting. HW defined TX FIFO sizes may not always be
sufficient for these compositions. By utilizing flexible TX FIFO
allocation, this allows for endpoints to request the required FIFO depth to
achieve higher
Some UDCs may have constraints on how many high bandwidth endpoints it can
support in a certain configuration. This API allows for the composite
driver to pass down the total number of endpoints to the UDC so it can verify
it has the required resources to support the configuration.
Changes in V7:
- Added a new property tx-fifo-max-num for limiting how much fifo space the
resizing logic can allocate for endpoints with large burst values. This
can differ across platforms, and tie in closely with overall system latency.
- Added recommended checks for DWC32.

Dear Masami and Steve,
I have sent v2 but still have confusions:
OK, I think it is simpler to check the rp->kp.addr && rp->kp.symbol_name
