Add support to request SoC stat from firmware through HTT stat
type 38. This stat gives drop count of SoC.

Note: MCC firmware version -
WLAN.HMT.1.0-03427-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.15378.4 does not
support tag HTT_STATS_SOC_TXRX_STATS_COMMON_TAG(125).

Sample output:
-------------
echo 38 > /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_SOC_COMMON_STATS_TLV:
soc_drop_count = 0x0000000000000000

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1
