[PATCH] media: docs: fimc: Update module build options

[Karl Mehltretter <kmehltretter@gmail.com>]

Commit 4af813108b88 ("[media] s5p-fimc: Add support for Exynos4x12
FIMC-LITE") turned VIDEO_SAMSUNG_S5P_FIMC into a menu and moved the
FIMC driver to the new VIDEO_S5P_FIMC option, but the build section
of fimc.rst still names the old symbol.

s5p-csis.ko has always been controlled separately by
VIDEO_S5P_MIPI_CSIS, so building FIMC as a module does not produce
both modules. Describe each module with its own option.

-If the driver is built as a loadable kernel module (CONFIG_VIDEO_SAMSUNG_S5P_FIMC=m)
-two modules are created (in addition to the core v4l2 modules): s5p-fimc.ko and
-optional s5p-csis.ko (MIPI-CSI receiver subdev).
+If the FIMC driver is built as a loadable kernel module
+(CONFIG_VIDEO_S5P_FIMC=m), it is named s5p-fimc.ko.  The optional
+MIPI-CSIS receiver is controlled separately by CONFIG_VIDEO_S5P_MIPI_CSIS
+and is named s5p-csis.ko when built as a module.
