[Xenial SRU][PATCH 1/1] ath10k: add max_tx_power for QCA6174 WLAN.RM.2.0 firmware

[Shrirang Bagul]

From: Alan Liu <alanliu at qca.qualcomm.com>

BugLink: https://bugs.launchpad.net/bugs/1736317

QCA6174 WLAN.RM.2.0 firmware uses max_tx_power instead of using max_reg_power
to set transmission power. The tx power was about -50dbm, after applying this
change, it become -32dbm.
