mt8365: spm: add rgu notify in suspend/resume flow
requested to merge mediatek/aiot/team-mtk-aiot-sw-ss2/trusted-firmware-a:ryan/8365_suspend_rgu_notify into mtk-v2.6
add rgu suspend notify before system suspend and rgu resume notify after system resume. This can avoid system be auto-rebooted by hardware watchdog in suspend status.
FIX: AIOT-1171
