qcacmn: Find proper radar-found secondary frequency
Bring up a Hawkeye AP in ETSI domain in HT80_80 mode and enable preCAC
(preCACEn). When preCAC timer is running, if radar gets detected in the
secondary segment (which is DFS), radar found frequency gets computed
from "dfs_precac_secondary_freq" variable which does not get populated
for Lithium chipsets as "dfs_precac_secondary_freq" is specific to
legacy preCAC.
Since the secondary frequency gets assigned as 0, radar found offset gets
computed wrongly and channels are not added to NOL.
Ensure that "dfs_precac_secondary_freq" is used for secondary frequency
computation only for legacy chips. For chips that have a separate agile
radar detector engine, use "dfs_ch_vhtop_ch_freq_seg2" variable to
compute the secondary frequency.
