Diogo Ivo 660b299bed Revert "drm/tegra: dsi: Clear enable register if powered by bootloader" 
Commit b6bcbce335 ("soc/tegra: pmc: Ensure power-domains are in a
known state") was introduced so that all power domains get initialized
to a known working state when booting and it does this by shutting them
down (including asserting resets and disabling clocks) before registering
each power domain with the genpd framework, leaving it to each driver to
later on power its needed domains.

This caused the Google Pixel C to hang when booting due to a workaround
in the DSI driver introduced in commit b22fd0b963 ("drm/tegra: dsi:
Clear enable register if powered by bootloader") meant to handle the case
where the bootloader enabled the DSI hardware module. The workaround relies
on reading a hardware register to determine the current status and after
b6bcbce335 that now happens in a powered down state thus leading to
the boot hang.

Fix this by reverting b22fd0b963 since currently we are guaranteed
that the hardware will be fully reset by the time we start enabling the
DSI module.

README 

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.
