This patch adds new V4L2_CAP_VIDEO_M2M and V4L2_CAP_VIDEO_M2M_MPLANE
capability flags that are intended to be used for memory-to-memory (M2M)
devices, instead of ORed V4L2_CAP_VIDEO_CAPTURE and V4L2_CAP_VIDEO_OUTPUT.
V4L2_CAP_VIDEO_M2M flag is added at the drivers, CAPTURE and OUTPUT
capability flags are left untouched and will be removed in future,
after a transition period required for existing applications to be
adapted to check only for V4L2_CAP_VIDEO_M2M.

Tidy up the variant and driver data handling. Remove the 'samsung_'
prefix from some data structures since it doesn't really carry any
useful information and makes the names unnecessarily long.

Prefix the pixel format enumerations with FIMC_FMT_ to make it more clear,
especially when used in new IP drivers, like fimc-lite, etc. Also add IO_
prefix in the input/output enumeration.

Simplify the register API and use FIMC_REG_ prefix for all register
definitions for consistency with FIMC-LITE. The unused image effect
defines are removed.

In order to be able to select only FIMC-LITE support, which is added
with subsequent patches, the regular FIMC support is now contained
only in fimc-core.c, fimc-m2m.c and fimc-capture.c files. The graph
and pipeline management is now solely handled in fimc-mdevice.[ch].
This means the FIMC driver can now be excluded with Kconfig option,
leaving only FIMC-LITE and allowing this driver to be reused in SoCs
that have only FIMC-LITE and no regular FIMC IP.

Virtually no functional changes, just code reordering. This let us to
clearly separate all logical functions available in the driver: fimc
capture, mem-to-mem, and later fimc-lite capture, ISP features, etc.
