TI CC32xx does not support binding the same port to multiple sockets,
but instead uses the IPv6 socket to handle both IPv4 and IPv6
connections. This commit modifies the sample to reflect this.
In addition, Kconfig options are overridden in order for the sample
to take advantage of wifi and socket offloading on this platform.
