qcacld-3.0: Bring up SAP in VLP if country supports VLP

In STA+SAP concurrency, if the STA is connected in indoor
power, and if the country/channel supports VLP, then bringup
the SAP in VLP. Move the STA to VLP as well.

Restore the power of the STA, when the SAP is disconnected.

Add changes to:
a) Decide the power type for the concurrency during start bss,
stop bss, change channel request calls of the SAP interface.

b) Allow the 6 GHz SCC channel in ACS computation if the channel
supports VLP power or if the channel is indoor and enabled.
