ports/rp2/boards/W5100S_EVB_PICO/mpconfigboard.cmake: Set default LWIP mode to Disable

The W5100S and W5500 modules are optimized for hard-wired settings.

So, I suggest to set the default mode to Hard wired (='LwIP 0')
Based on performance tests conducted with iperf3,
it was found that the bitrate of the device in hard-wired mode is 74% higher than the LwIP.
(LWIP: 747 kbits/sec, Hardwired: 1.34Mbits/sec)

Therefore, to enhance the default network speed and performance for users.
Please refer to the following post for speed measurement using iperf3
