Neil Armstrong d3cac7d030 media: meson/ao-cec: move cec_notifier_cec_adap_register after hw setup 
[ Upstream commit 3e84a18a259e1df35e5b549ab92ec3baf82ff010 ]

When probed after the HDMI notifier, calling cec_notifier_cec_adap_register()
calls the enable() adapter callback, but the HW is not yet set up.

Moving cec_notifier_cec_adap_register() right before cec_register_adapter()
fixes the following crash:
Ignoring spurious kernel translation fault at virtual address 0000000000000008

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 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.
