drm/vc4: crtc: Make sure the HDMI controller is powered when disabling 
Since commit 875a4d5368 ("drm/vc4: drv: Disable the CRTC at boot
time"), during the initial setup of the driver we call into the VC4 HDMI
controller hooks to make sure the controller is properly disabled.

However, we were never making sure that the device was properly powered
while doing so. This never resulted in any (reported) issue in practice,
but since the introduction of commit 4209f03fcb8e ("drm/vc4: hdmi: Warn
if we access the controller while disabled") we get a loud complaint
when we do that kind of access.

Let's make sure we have the HDMI controller properly powered while
disabling it.

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.
