This board uses RPMH, specifies "regulator-allow-set-load" for LDOs, but doesn't specify any modes with "regulator-allowed-modes". Prior to commitefb0cb50c4("regulator: qcom-rpmh: Implement get_optimum_mode(), not set_load()") the above meant that we were able to set either LPM or HPM mode. After that commit (and fixes [1]) we'll be stuck at the initial mode. Discussion of this has resulted in the decision that the old dts files were wrong and should be fixed to fully restore old functionality. Let's re-enable the old functionality by fixing the dts. NOTE: while here, let's also remove the nonsensical "regulator-allow-set-load" on the fixed regulator "vreg_s4a_1p8".

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.
