fix(n1sdp): add platform-specific power domain functions

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

This commit uses the previous fix in platform-specific implementations
of power domain off/suspend functions.
