CONFIG_CHAN_NUM_API macro will be disabled. Remove all the references to
any function defined/declared under the macro. The function
reg_get_channel_list_with_power was placed under CHAN_NUM_API by mistake.
This API does not have any CHAN_FREQ_API counterpart. Therefore, move
this function out of CHAN_NUM_API macro.
The function dfs_send_radar_ind_for_freq is redundant as its counterpart
dfs_send_radar_ind has the same arguments and same functionality,
removing the function dfs_send_radar_ind_for_freq. The function
dfs_send_radar_ind is moved out of CHAN_NUM_API macro.
The function wlan_reg_chan_to_freq, wlan_reg_legacy_chan_to_freq is
moved out of CONFIG_CHAN_NUM_API macro. Since it is applicable for legacy
bands.
