qcacld-3.0: Do not allow SAP SCC on non-PSC/non-VLP channels

SAP is allowed to come up on SCC with a STA operating
in 6 GHz only if the STA is on a PSC channel in VLP mode.
Therefore, filter out all 6 GHz channels from the PCL if
the STA operates on any non-VLP mode. Also, in case of
VLP mode, filter out non-PSC channels.
