While looking at reboot issues and module load/unload tests, I found
out some resources allocated in the dailink .init() callback are not
properly released - there is no existing mechanism in the soc-core to
do so.
The addition of a dailink .exit() callback seems to be the simplest
solution overall. It can be argued that the existing machine platform
device .remove() callback can also perform the necessary cleanups,
however as shown in the last two examples this might require a loop to
identify components whereas the dailink .exit() already has all the
necessary information to revert the actions done in the .init() step.
Changes since RFC:

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.
