Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=c064268eb8ed5c9a809ae0e5d9104a343a81d206

--------------------------------

commit 98d504a8 upstream.

The spread of capability between the three WiFi silicon parts wcn36xx
supports is:

wcn3620 - 802.11 a/b/g
wcn3660 - 802.11 a/b/g/n
wcn3680 - 802.11 a/b/g/n/ac

We currently treat wcn3660 as wcn3620 thus limiting it to 2GHz channels.
Fix this regression by ensuring we differentiate between all three parts.
