Subject: [PATCH AUTOSEL 4.19 018/209] mt76x2: fix tx power configuration for VHT mcs 9

From: Lorenzo Bianconi <lorenzo.bianconi@...hat.com>

[ Upstream commit 60b6645ef1a9239a02c70adeae136298395d145a ]

Fix tx power configuration for VHT 1SS/STBC mcs 9 since
in MT_TX_PWR_CFG_{8,9} mcs 8,9 bits are GENMASK(21,16) and
GENMASK(29,24) while GENMASK(15,6) are marked as reserved
