drivers: wifi: Disable workaround for anomaly 159

The proper workaround would be to use 64MHz CPU that will impact Wi-Fi performance, and as its never been seen so far, disable the workaround, and this can be revisited in the future. Fixes SHEL-2636. Signed-off-by: Chaitanya Tata <[email protected]>
