media: rc: add missing io.h

Patch series "kfifo: Clean up kfifo.h", v2.

To reduce dependency hell a degree, clean up kfifo.h (mainly getting rid
of kernel.h in the global header).  


This patch (of 3):

In many remote control drivers the io.h is implied by others.  This is not
good as it prevents from cleanups done in other headers.  Add missing
include.
