qcacld-3.0: add api to check if the channel is allowed for sap

Browse Source 
Check the factors as below to decide whether the channel is
allowed or not:
 * If the channel is in LTE coex channel avoidance list;
 * If it's STA+SAP SCC;
 * If STA+SAP SCC on LTE coex channel is allowed.

Replace policy_mgr_is_safe_channel() with this new function
for sap channel selection and acs channel filtering, to allow
unsafe channels when it's STA+SAP SCC and STA+SAP SCC on LTE
coex channel is allowed.
