ath10k-ct: select mac80211 debugfs support

Trying to compile ath10k-ct without mac80211 debugfs support will result in:
openwrt/build_dir/target-arm_cortex-a15+neon-vfpv4_musl_eabi/linux-ipq806x_generic/ath10k-ct-regular/ath10k-ct-2024.07.30~ac71b14d/ath10k-6.10/wmi.h:8083:2: error: #warning Please enable ATH10K-DEBUGFS kernel option for optimal support for CT firmware. [-Werror=cpp]
 8083 | #warning Please enable ATH10K-DEBUGFS kernel option for optimal support for CT firmware.
      |  ^~~~~~~
cc1: all warnings being treated as errors

So, since the driver itself is saying that debugfs is required, then
lets make ath10k-ct select mac80211 debugfs support which is selected
by default anyway.
