wifi: ath12k: Support DMAC Reset Stats

Add support to request DMAC reset stats from firmware through HTT stats
type 45. These stats give debug SoC error stats such as reset count, reset
time, engage time and count, disengage time and count and destination
ring mask.

Sample output:
-------------
echo 45 > /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
HTT_DMAC_RESET_STATS_TLV:
reset_count = 1
reset_time_ms = 3013430342
disengage_time_ms = 3013430342
engage_time_ms = 3013430342
disengage_count = 1
engage_count = 1
drain_dest_ring_mask = 0x0
