Tegra194: Request CG7 from last core in cluster
- SC7 requires all the cluster groups to be in CG7 state, else
is_sc7_allowed will get denied
- As a WAR while requesting CC6, request CG7 as well
- CG7 request will not be honored if it is not last core in Cluster
group
- This is just to satisfy MCE for now as CG7 is going to be defeatured
