Now that the Buffalo-specific initvals have been
moved to a separate array, update the default high
power TX gain table for all AR9300 v2.2 devices.

The Buffalo device WZR-HP-G450H uses the index 3 for TX gain,
which is set to the high_power table currently. Later variants
of the router use the same index, but instead refer to the
low_ob_db gain table. This is not handled in the driver since
there is no way to distinguish board revisions and the high_power
table is used (incorrectly) for the newer variants.

By default, devices based on AR9300 using the TX gain index 3 have
to use the high_power table. To make sure that WZR-HP-G450H is not
broken when the high_power table is updated, use a separate array
based on information obtained from the platform data.

The current situation where only the original variant of WZR-HP-G450H
works properly stays unchanged.

Rewrite the search cycle state machine to use a more data
oriented approach where the different Tx columns (configs)
limitations and next columns to search are reprsented in
tables which are easy to change. This overhaul also includes
several major fixes:

1. Prevent going back to a specific Tx column in a search
cycle if it was already explored.

2. Avoid switching to a Tx column that doesn't have any chance
if it performs perfectly to beat the current throughput we're
getting.

These issues were degrading throughput as they were causing
switching to "bad" Tx columns.

The table rs_ht_to_legacy is used to get the next legacy rate
following the last HT or VHT rate in the LQ rates table.
The mapping wasn't correct as well as didn't include entries
for MCS8/9 which led to out of bounds access. This didn't
trigger a crash but led to legacy rate entries using 1Mbps
rate.
In 5Ghz this probably caused the Tx to fail completely given
that Tx attempt would have reached the legacy entries and 1Mbps
isn't valid.
