Subject: [PATCH 2/2] soc: qcom: aoss: Use GENPD_FLAG_SUSPEND_ON flag

All the power domains exposed as part of AOSS QMP driver require to stay
powered on for suspend. They are powered on when the remote processors
boots up and powered off on remote processor crash/shutdown. Mark the
power domains with GENPD_FLAG_SUSPEND_ON to model this behavior.
