Tx status reporting cannot account for the tx attempt starting at a rate
further down the chain, so without this flag it leads to inaccurate
results.

There were a number of issues in the existing tx power handling code:
1. The EEPROM target power for chain 0 refers to the actual output power
after the channel and bandwidth delta have been added to the initial
channel gain. This means the delta values should not be added/subtracted
for the rate power calculation
2. When power is reduced significantly, the initial channel gain
underflows very quickly, while the per-rate power offsets are high.
This miscalculation causes effective tx power to be increased when it
should actually be lowered.
Fix this by trying to adjust the channel gain to the lowest power from
the rate table. In case of under- or overflow, compensate by adding an
appropriate delta to the rate power values.
This makes power configuration more accurate on a wider range of
configurable values

Fix hw queue configuration since mt76x2 devices use a reverse queue
enumeration respect to mac80211 one:
- 0: AC_BE
- 1: AC_BK
- 2: AC_VI
- 3: AC_VO
The issue can be reproduced sending two concurrent flow using
two separate queues:
- VO: 20Mbps UDP traffic
- BE: TCP traffic
In this scenario the UDP traffic will be blocked by the TCP one.
Fix it configuring properly WMM hw queue parameters
