ath10k: add wmi service peer stat info for wmi tlv

ath10k_sta_statistics is used to report info for iw wlan0 link,
it check ath10k_peer_stats_enabled, and ath10k_peer_stats_enabled
check WMI_SERVICE_PEER_STATS bit of ar->wmi.svc_map. SVCMAP() for
WMI_SERVICE_PEER_STATS was defined only for wmi_10x_svc_map and
wmi_10_4_svc_map interfaces, it missed in wmi_tlv_svc_map, so it is
not usable for iw wlan0 link for wmi tlv interface.

If firmware report WMI_TLV_SERVICE_PEER_STATS_INFO for wmi tlv, then
enable the WMI_SERVICE_PEER_STATS bit in ath10k, and then it pass check
in ath10k_peer_stats_enabled and ath10k_sta_statistics pass check.
