The background for this is that I'm building a distribution-style
multiplatform kernel, that is to say a kernel which can boot on a big
set of different ARM boards. As such, the intention is to keep the core
zImage as small as possible and essentially build things as far as
possible as loadable modules. So in a sense, all of the hardware is
"hotplugged", depending on which board the kernel is actually booted on!

For that use-case, exynosdrm needs to be able to build as a module
(which it already can!) and it needs the required meta-data for
userspace to know when it should be loaded. The latter is what my patch
adds.
