[PATCH v2] wcn36xx: Disable 5GHz for wcn3610

[Ramon Fried]

wcn3610 can only operate on 2.4GHz band due to RF limitation.
If wcn36xx digital block is associated with an external IRIS
RF module, retrieve the id and disable 5GHz band in case of
wcn3610 id.

v2: fixed wrong assignment, which is logically introduces the 
	same behaviour, but for correctness.
