This patch supports the creation and deletion of JETTY.
Compared with the JFS/JFR programming mode, JETTY provides both sending
and receiving functions. In the sending direction, JETTY contains a JFS
that supports sending messages to multiple destination nodes. In the
receive direction, JETTY contains a JFR that can receive data from
different nodes. JFS and JFR in JETTY can point to different JFCs.
When creating a JETTY, the depth and attributes of the JFS and JFR
contained in the JETTY need to specified. UDMA driver will allcate
memory resources and configure the hardware(QP Context and SRQ Context).
