From: Ben Greear <greearb@candelatech.com>
Add tx-mode (ofdma, ht, vht, HE) histogram,
tx-ru-idx histogram, and tx-bandwidth histogram.
Also add tx attempts and tx success counters.
All of this is per-station.

The tx status callback is not called for every frame, so
those specific counters under-count, but at least they give
some idea of what is going on.

I think you can drop WARN_ON_ONCE here since we already have dev_err()

From: Ben Greear <greearb@candelatech.com>
These counters are clear-on-read, so we need to accumulate
them in the update_stats poll logic, and read the accumulated
values instead of directly doing register reads when reporting
to debugfs and ethtool stats.

At 160, this chip can only do 2x2 NSS. Fix the features
accordingly, verified it shows up properly in iw phy foo info
now.

Add register definitions and read & accumulate them in
the mib polling logic. Note that some registers should not
be read since firmware is already reading them. If driver
reads those, they will be cleared-on-read, and so the firmware
stats will be incorrect.
For these 'do-not-read' stats, add them to the registers definition
so that other developers can be aware of these constraints, but do
not actually read them in the driver.
