wifi: ath12k: Add support RX PDEV stats

Add support to request and receive RX pdev firmware stats using HTT
stats type 2. This stats type reports PPDU and MPDU counters, firmware
ring and buffer statistics, and RX suspend and resume counts.

Note: Currently, firmware on mobile-centric chipsets do not maintain
      these statistics, so a query will not return any information.

Sample output:
-------------
echo 2 >/sys/kernel/debug/ath12k/pci-0000\:58\:00.0/mac0/htt_stats_type
cat /sys/kernel/debug/ath12k/pci-0000\:58\:00.0/mac0/htt_stats
