wifi: ath12k: Support Transmit DE stats

Browse source 
Add support to request transmit DE stats from firmware through HTT stats
type 8. These stats give information about enqueued packets, discarded
packets, failed packets and other information such as power, bandwidth
information, number of retries, etc.

Sample output:
-------------
echo 8 > /sys/kernel/debug/ath12k/pci-0000\:06\:00.0/mac0/htt_stats_type
cat /sys/kernel/debug/ath12k/pci-0000\:06\:00.0/mac0/htt_stats
