Device trees for newer SoCs avoid defining the regulator nodes directly in the SoC device tree (here: msm8916.dtsi). The reason for this is that theoretically it is possible to combine the SoC with a different PMIC, or to use all the regulators in a board-specific way. Therefore let's remove those from the SoC include (msm8916.dtsi). In practice, pretty much all MSM8916 boards were combined with PM8916, and use the regulators in similar ways. After looking at many different MSM8916 boards (mostly smartphones and tablets), I haven't seen a single device that isn't using the same regulators for components integrated into the SoC. If all boards end up defining all regulators and supplies in the same way then it is useful to have an include for that, so we can avoid duplicating it everywhere. If there is really a super special board that does it differently it could just override some properties or avoid using the include altogether. This patch moves the regulator and common supply definitions to a new include called "msm8916-pm8916.dtsi". This is also going to be useful when introducing CPR (Core Power Reduction) later because we can configure the CPU regulator (pm8916_spmi_s2) for all devices in this common include.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
