wcn36xx: Implement tx_rate reporting
Currently, the driver reports a tx_rate of 6.0 MBit/s no matter the true
rate:
root@linaro-developer:~# iw wlan0 link
Connected to 6c:f3:7f:eb:9b:92 (on wlan0)
SSID: SQ-DEVICETEST
freq: 5200
RX: 4141 bytes (32 packets)
TX: 2082 bytes (15 packets)
signal: -77 dBm
rx bitrate: 135.0 MBit/s MCS 6 40MHz short GI
tx bitrate: 6.0 MBit/s
bss flags: short-slot-time

This patch requests HAL_GLOBAL_CLASS_A_STATS_INFO via a hal_get_stats
firmware message and reports it via ieee80211_ops::sta_statistics.

Tested on MSM8939 with WCN3680B running firmware CNSS-PR-2-0-1-2-c1-00083,
and verified by sniffing frames over the air with Wireshark to ensure the
MCS indices match.
