PMP8074 is a companion PMIC to the Qualcomm IPQ8074 series that is
controlled via SPMI.
Add DTSI for it providing GPIO, regulator, RTC and VADC support.
RTC is disabled by default as there is no built-in battery so it will
loose time unless board vendor added a battery, so make it optional.

Changes in v7:
* Dual license with BSD-3-Clause
* Use "-" instead of underscores in node names
Changes in v6:
* Add RTC and GPIO nodes
Changes in v5:
* Remove #address-cells and #size-cells as they are not required for
regulator subnodes
