[PATCH] zd1211rw: Add ID for ZyXEL M-202 XtremeMIMO

Tested by Nathen Meyers
FCC ID: SI5WUB221Z
zd1211b chip 0586:340a v4810 high 00-13-49 AL2230_RF pa0 ----S

Despite the product name, I'm pretty sure this isn't a MIMO device. It
appears just to be a normal ZD1211B and we have never heard of these
devices having more than 1 RF. I guess they named this product this way
to make it appear that it fits in with the rest of their XtremeMIMO
product range.
