USB: ci13xxx_udc: Add support for large requests
Spanning large request into multiple dTDs will fail with short
packets. Instead queue one dTD at a time. This patch has
the following limitations.
1. Large requests are supported only on Bulk OUT endpoints. This
feature is mainly required for MTP driver to achieve better write
throughputs. The VFS performs well with larger buffers.
2. To keep it simple, don't allow queuing while processing large
request. Don't allow larger request queuing while the queue is
busy.
