Realtek RTL8195A prints debug info by default for WiFi

[bulislaw]

I just extended WiFi example to support RTL8195A and it works, which is great! ARMmbed/mbed-os-example-wifi#40

The board is printing some info on serial I'd rather not have by default thought:

Done

All the lines prefixed with RTL8195A[Driver] and ioctl[SIOCGIWESSID] should be hidden by default. I would recommend adding verbose parameter to the constructor defaulting to false that would toggle printing of whatever extra information you see fit, but by default you shouldn't print anything (except hard errors maybe).

RTL8195A[Driver] message is sent from inside of our lib, so we'll try to add a switch for these debug messages. Thanks for the advice.

They are always ON at the moment? It would be great to have it optional, and by default OFF.

We create this PR to mute the debug messages mentioned here. #4667

I think issue can be closed now, PR #4667 is merged. @bulislaw

[Archcady]

IS this issue still open?

[JanneKiiskila]

@0xc0170 @bulislaw - it's not open anynmore, this issue should be closed (like my comment 12 days ago already suggested).
