Commit 4d8c18196378824e388cf31ef991ba8fbbb09cbf added a redistributor
power off to resolve an error on N1SDP/Morello. Prior to this fix,
turning off both cores in a cluster would cause a hang when powering
back on either core. This change introduced issues on other platforms
with a different GIC implementation, and was reverted in commit
60719e4e0965aead49d927f12bf2a37bd2629012.
This commit uses the previous fix in platform-specific implementations
of power domain off/suspend functions.

Commit 4d8c18196378824e388cf31ef991ba8fbbb09cbf
introduced an invalid redistributor power off
where we turn off the redistributor without
checking if the system power domain level is
turning off, otherwise we can turn off a
redistributor when other cores or clusters are
sharing it, also if it does indeed needs
powering off during suspend we do it twice.
This change fixes this by checking on the
system power state first then turning off
the redistributor.

Turn ON/OFF GIC redistributor in sync with GIC CPU interface ON/OFF.
Issue :
The Linux prompt hangs when all the cores in a cluster are turned OFF
and we try to turn ON a core in that cluster. Previously when TF-A turns
ON a core, TF-A first turns ON the redistributor followed by the core.
This did not match the flow when turning OFF a core, as TF-A did not
turn OFF redistributor when the corresponding core[s] are disabled.
This hang is resolved by disabling redistributor as cores are disabled,
keeping them in sync.
