In order to give a much better approximation of the real channel noise, add the difference between the measured noise floor and the nominal chip specific noise floor to the default minimum channel noise value, which is currently used to calculate the signal strength from the RSSI value. This may not be 100% accurate, but it's much better than what's there before. Signed-off-by: Felix Fietkau Signed-off-by: John W.

The override caused the driver to always use the 'normal' power tables even for high power devices if their minor version was not high enough. Thus leading to reduced power output. This isn't needed for the AR9285; the check originated with the AR9280 setup code which requires the EEPROM version check.
