qcacld-3.0: Update fourth connection PCL table to avoid MCC

If MLO STA connect with one 5 GHz low link and another 6 GHz (non-PSC)
link, and start 2 SAP on 5 GHz band, one SAP will start on 5 GHz low
channel doing SCC, another SAP will not start on 6 GHz (non-PSC)
channel and start on 5 GHz high doing MCC.

Add one PCL type which add SCC on 5 GHz low channel to
PM_SCC_ON_5G_HIGH_5G_HIGH_PLUS_SHARED_2G for this case, so that last
SAP can start on 5 GHz low channel doing SCC.
