mox-support: update SDIO firmware
We received a new SDIO firmware from NXP. The difference that it should fix dropping connection to Wi-Fi if there is running iperf.
Checksum SHA256 of binary: 1f725e4f92bff871d031f625d58a4feeb390703f75d5190e2934ebe717d6a265
FW was provided to by me @prohar if I am not wrong if testing goes well then we will update it in linux-firmware, don't we?
