wifi: ath11k: Add HTT stats for PHY reset case

New HTT stats are added with stats type 37 to
provide PHY reset stats and PHY reset counter stats.

PHY reset stats are used to display the current
PHY-related operation information such as band, CCA
threshold, current operating channel etc.,

PHY reset counter stats are used to display the
PHY reset counter values like calibration counts,
temperature based recalibration counts etc.,

Usage:
echo 37 > /sys/kernel/debug/ieee80211/phyX/ath11k/htt_stats_type
cat /sys/kernel/debug/ieee80211/phyx/ath11k/htt_stats
