drm/exynos: fimd: Guard display clock control with runtime PM calls 
Commit c9b1150a68 ("drm/atomic-helper: Re-order bridge chain pre-enable
and post-disable") changed the call sequence to the CRTC enable/disable
and bridge pre_enable/post_disable methods, so those bridge methods are
now called when CRTC is not yet enabled.

This causes a lockup observed on Samsung Peach-Pit/Pi Chromebooks. The
source of this lockup is a call to fimd_dp_clock_enable() function, when
FIMD device is not yet runtime resumed. It worked before the mentioned
commit only because the CRTC implemented by the FIMD driver was always
enabled what guaranteed the FIMD device to be runtime resumed.

This patch adds runtime PM guards to the fimd_dp_clock_enable() function
to enable its proper operation also when the CRTC implemented by FIMD is
not yet enabled.

Fixes: 196e059a8a ("drm/exynos: convert clock_enable crtc callback to pipeline clock")

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.
