As mentioned in the previous patchset, this kind of control should be
better provided as a module option. If this influences on the module
dependency, it'd make sense to do as Kconfig. But this doesn't look
so, and it's rather a sort of runtime control to match with the
deployed hardware configuration.
In the previous patch set, there were two Kconfigs. One of them was for
debug, but I removed it since it wasn't such a good idea. This one is
more static and can be enabled by default by a distro. It's not intended
to be changed at runtime. I just wanted to leave it out for now to make
sure there is no change to existing platforms. I can remove it if you
feel it's unnecessary.
