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.
