media: Add a Kconfig option for the Request API
The Request API is now merged to the kernel but the confidence on the
stability of that API is not great, especially regarding the interaction
with V4L2.
Add a Kconfig option for the API, with a scary-looking warning.
The patch itself disables request creation as well as does not advertise
them as buffer flags. The driver requiring requests (cedrus) now depends
on the Kconfig option as well.
