Jim Jun / Mbed 2 deprecated WebSocketClient_Chat_WIZwiki-W7500

Chat by using websocket on WIZwiki-W7500 platform. Recently WIZwiki-W7500 platform was announced by WIZnet. So I implemented a firmware of WIZwiki-W7500 by changing UART definition because I can handle a source code easily.

Dependencies:   WIZnetInterface WebSocketClient mbed
