Support 320 MHz PHY configuration and while doing so rewrite
the code since we'd otherwise double the number of cases in
the switch statement.

From: Mordechay Goodstein <mordechay.goodstein@intel.com>
Rate scale needs to be configured to what MCS it can use per BW and NSS,
this is done by parsing our capabilities of TX and peer's capabilities of
RX and setting the minimum for rate scale usage.
Also do some cleanup removing redundant enum defines not used by
FW/Driver.

In an EHT connection fill in the HE context command
with PPE Thresholds field from EHT Capabilities IE.
If PPE Thresholds field presents only in HE Capabilities IE,
take the thresholds from there.
If it's not present in both - set the Common Nominal Packet Padding
field from EHT Capabilities IE.

The bits are reserved on the opposite bands, so we shouldn't
always send them, only the 2G bit on 2.4 GHz and the 5G bits
on 5/6GHz. Fix that.

We can't have it in AP mode unless for debug, since we don't have
160 MHz in HE PHY capabilities, and also set it only in 6 GHz even
if (unlike in HE) it's always defined.
