wifi: rtw89: phy: dynamically adjust EDCCA threshold

Browse source 
Add dynamic mechanism EDCCA (Energy Detection Clear Channel Assessment)
in track work. Using a fixed-value threshold will make EDCCA particularly
sensitive and cause failure to transmit under certain circumstances.
Therefore, the threshold is dynamically adjusted to make EDCCA suitable
for any situation.

However, in some cases, we will adjust the EDCCA threshold to the highest
level so that urgent transmissions can be performed successfully, such as
scanning.

Finally, in order to observe the EDCCA report in time, add the EDCCA perIC
register macro and EDCCA HW report analysis. EDCCA logs can be displayed
by using the EDCCA debug mask.
