wlan: mac: remove obsolete Factory Test Mode featurization

The current code supports having both Factory Test Mode and Mission
Mode available in one driver.  But this code has evolved over time
from a code base which initially only supported having separate
Factory Test Mode and Mission Mode drivers, with conditional
compilation used to create the two versions.  Since this conditional
compilation is no longer necessary, remove it.
