[PATCH v12 8/8] arm64: dts: mediatek: Add MediaTek MT6392 PMIC dtsi

[Luca Leonardo Scorcia]

From: Val Packett <val@xxxxxxxxxxxx>

Add the dtsi to be included by all boards using the MT6392 PMIC,
providing support for regulator, keys, pinctrl and RTC.

Import the new file in the shared device tree for the Pumpkin boards and
declare the regulators that must be enabled at boot for proper operation.
