Add mt76x02_phy_set_txpower utility routine in mt76x02_phy.c in order to be reused in mt76x0 tx power management code. Moreover move following routines in mt76x02-lib module: - mt76x02_tx_power_mask - mt76x02_get_max_rate_power - mt76x02_limit_rate_power - mt76x02_add_rate_power_offset Signed-off-by: Lorenzo Bianconi <[email protected]> Signed-off-by: Felix Fietkau <[email protected]>
