[RFC PATCH] ARM: exynos_defconfig: Enable Samsung media platform drivers as modules

[Javier Martinez Canillas]

There are a bunch of media platform drivers under drivers/media/platform/
that are for Samsung SoCs but are not being built with exynos_defconfig.

This patch enables them as a module to improve build coverage for these
drivers and also to allow people use them with proper hardware if modules
are installed. The S5P MFC driver wasn't enabled since it fails to probe.

Only the boolean Kconfig symbols are enabled as built-in, since drivers
are not critical and also to keep the kernel binary image size as small
as possible.

Hello Kukjin and Krzysztof,

I'm posting this as a RFC because I don't know if it will add too much bloat
to a kernel built with exynos_defconfig.

I think it doesn't since the image size only increased 15 KiB which seems to
be a small price for having these built, but you may have another opinion.

Best regards,
Javier
