qcacld-3.0: Add STA+SAP indoor channel scc support

Based on the ini "sta_sap_scc_on_indoor_chan" the behavior of
STA+SAP in scc is as follows:
1. STA is on 2.4 GHz & SAP is on 2.4 GHz and SAP user configured
initial channel was on 5 GHz, then move SAP to 5 GHz initially
started channel

2. When STA + SAP are doing SCC on indoor only channel and
  a) STA moves to 2.4 GHz -> then SAP moves to initialy started
channel
  b) STA moves to another indoor only channel -> SAP follows
STA channel
  c) STA moves to non-indoor, non-dfs channel -> SAP follows
STA channel.
  d) STA moves to DFS channel -> SAP moves to 2.4 GHz channel
  e) STA disconnects -> Move SAP to initially started channel

3. STA is on 2.4 GHz & SAP is on 5 GHz non-indoor, non-dfs channel
and STA moves to 5 GHz channel, then SAP should follow STA to 5 GHz
if SAP was initially started on 5 GHz channel. Else SAP restart
is not required and SAP will remain on the 2.4 GHz channel
