When switching between low gain (high RSSI) and high gain settings, it
can take a few seconds to adjust to the current environment.
This can lead to short periods of time with extreme packet loss.
When switching from low_gain=1 to low_gain=2, start with the same gain
adjustment value instead of the lowest to avoid spikes of huge numbers
of false CCA events
Also avoid resetting adjustment values on switching between low_gain
values 0 and 1, since it affects only the upper limit of vga adjustment

The range should only be limited to 4 for really weak signals, for all
other gain settings the range is 16.

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
