The PCIe PHY requires two regulators and are present on the SoM directly, while the PCIe connector also exposes 3V3 and 12V power rails which are available on the baseboard. Considering that 3/4 regulators are always-on on HW level and that the last one depends on a regulator from the PMIC that is specified as always on, this commit should be purely cosmetic and no change in behavior is expected. Let's add all regulators for PCIe on RK3399 Puma Haikou.

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 reStructuredText 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.
