There is a patch in linux-next (which I cannot find on lkml), which
breaks the build on s390x:
4be5e8648b0c287aefc6ac3f3a0b12c696054f43 is the first bad commit

As CEC support doesn't depend on MEDIA_SUPPORT, let's
place the platform drivers outside the media menu.
As a side effect, instead of depends on PCI, seco driver
can select it (and DMI).
