Add rtc and suspend to ram for Maxim MAX77686 PMIC

The Maxim MAX77686 family of PMICs supports RTC crystal clocks. Device tree bindings have been added to enable this feature across all devices.

Add information which regulators can be disabled during system suspend.

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').

Tested on Exynos4412 Odroid U3.
