The MAX77686 PMCI is able to power down and up key core supplies and other voltage rails via PWRREQ signal to enter / exit (deep) sleep mode. PWRREQ status is ignored during initial power up and down processes. All programming must be done before the AP enterns the sleep mode by pulling PWRREQ low since the AP does not have programming capability in (deep) sleep mode. Add suspend-to-mem node to regulator core to be enabled or disabled during system suspend and also support changing the regulator operating mode during runtime and when the system enter sleep mode (stand by mode). Regulators which can be turned off during system suspend: -LDOn : 2, 6-8, 10-12, 14-16, -BUCKn : 1-4. Use standard regulator bindings for it ('regulator-off-in-suspend').
