Convert the MFD part of Maxim MAX14577/MAX77836 MUIC to DT schema
format.  The example DTS was copied from existing DTS
(exynos3250-rinato.dts), so keep the license as GPL-2.0-only.

Thanks, fixed also regulator reference below and the regulator bindings
as in my other Maxim patches.

-Maxim MAX14577/77836 Multi-Function Device
-
-MAX14577 is a Multi-Function Device with Micro-USB Interface Circuit, Li+
-Battery Charger and SFOUT LDO output for powering USB devices. It is
-interfaced to host controller using I2C.
-
-MAX77836 additionally contains PMIC (with two LDO regulators) and Fuel Gauge.
-For the description of Fuel Gauge low SOC alert interrupt see:
-../power/supply/max17040_battery.txt
-
-
-Required properties:
-- compatible : Must be "maxim,max14577" or "maxim,max77836".
-- reg : I2C slave address for the max14577 chip (0x25 for max14577/max77836)
-- interrupts : IRQ line for the chip.
-
-
-Required nodes:
- - charger :
-	Node for configuring the charger driver.
-	Required properties:
-		- compatible : "maxim,max14577-charger"
-			or "maxim,max77836-charger"
-		- maxim,fast-charge-uamp : Current in uA for Fast Charge;
-			Valid values:
-			- for max14577: 90000 - 950000;
-			- for max77836: 45000 - 475000;
-		- maxim,eoc-uamp : Current in uA for End-Of-Charge mode;
-			Valid values:
-			- for max14577: 50000 - 200000;
-			- for max77836: 5000 - 100000;
-		- maxim,ovp-uvolt : OverVoltage Protection Threshold in uV;
-			In an overvoltage condition, INT asserts and charging
-			stops. Valid values:
-			- 6000000, 6500000, 7000000, 7500000;
-		- maxim,constant-uvolt : Battery Constant Voltage in uV;
-			Valid values:
-			- 4000000 - 4280000 (step by 20000);
-			- 4350000;
-
-
-Optional nodes:
-- max14577-muic/max77836-muic :
-	Node used only by extcon consumers.
-	Required properties:
-		- compatible : "maxim,max14577-muic" or "maxim,max77836-muic"
-
-- regulators :
-	Required properties:
-		- compatible : "maxim,max14577-regulator"
-			or "maxim,max77836-regulator"
-
-	May contain a sub-node per regulator from the list below. Each
-	sub-node should contain the constraints and initialization information
-	for that regulator. See regulator.txt for a description of standard
-	properties for these sub-nodes.
-
-	List of valid regulator names:
-	- for max14577: CHARGER, SAFEOUT.
-	- for max77836: CHARGER, SAFEOUT, LDO1, LDO2.
-
-	The SAFEOUT is a fixed voltage regulator so there is no need to specify
-	voltages for it.
