qca-wifi: Add ADFS compile-time macros

For a 16-MB profile, while insmoding "umac.ko" unknown symbol error for
function "dfs_translate_radar_params_for_agile_chan" is seen.

The actual definition of function
"dfs_translate_radar_params_for_agile_chan" is present in the
dfs_zero_cac.c which is not compiled for a 16-MB profile. Therefore,
the unknown symbol error is seen.

Add ADFS compile-time macros
QCA_SUPPORT_AGILE_DFS and QCA_SUPPORT_ADFS_RCAC to the declaration of the
ADFS specific function dfs_translate_radar_params_for_agile_chan().
As the macros are not present in 16-MB profile, the function becomes an
empty function in the zero_cac.h and definition of the function
dfs_translate_radar_params_for_agile_chan() is present (though empty)
in the umac.ko.
