dt-bindings: mfd: maxim,max14577: Convert to dtschema

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.

+description: |
+  This is a part of device tree bindings for Maxim MAX14577/MAX77836 MicroUSB
+  Integrated Circuit (MUIC).
+
+  The Maxim MAX14577 is a MicroUSB and Companion Power Management IC which
+  includes voltage safeout regulators, charger and MicroUSB management IC.
+
+  The Maxim MAX77836 is a MicroUSB and Companion Power Management IC which
+  includes voltage safeout and LDO regulators, charger, fuel-gauge and MicroUSB
+  management IC.
