qcacmn: Separate GET APIs for precac and agile precac flags

Currently a single API(dfs_get_precac_enable) is used to get
dfs_precac_enable and dfs_agile_precac_enable. This API is
wrongly returning value for dfs_precac_enable since agile
capability is set even for Cascade.

Separate out the GET APIs for getting dfs_precac_enable and
dfs_agile_precac_enable so that getting these flags becomes
independent of each other.
