fix(plat/synquacer): update scmi power domain off handling

Browse source 
In the SCMI power domain off handling, configure GIC
to prevent interrupt toward to the core to be turned off,
and configure CCN to disable coherency when the cluster is turned off.
The same operation is done in SCPI power domain off processing.

This commit adds the missing operation in SCMI power domain
off handling.
