[PATCH 7/7] arm64: dts: Add SC2731 PMIC dts file for Spreadtrum SC9860

[Baolin Wang]

The Spreadtrum SC9860 platform has one SC2731 PMIC, and the SC2731
PMIC integrates all mobile handset power management, audio codec,
battery management and user interface support function in a single
chip.

This patch adds the SC2731 dts file, as well as adding the RTC and
regulator device node for this PMIC.
