ath10k-ct: limit available channels via DT
This backports upstream commit 34d5629 ath10k: limit available channels via DT ieee80211-freq-limit to the 4.19 ath10k-ct version. Without this patch, disabled channels are still listed as a supported configuration for the radio. The identical patch was also backported by OpenWRT to the non-ct driver. It can be dropped as soon as we switch to an ath10k-ct version based on 4.20 or higher. Signed-off-by: David Bauer <email@example.com>

|There is already a DT property to limit the available channels but ath10k|
|has to manually call this functionality to limit the currrently set wiphy|
