Setting FIMC_REG_CITRGFMT_FLIP_X_MIRROR bit causes X-axis image
flip (vertical flip) and thus it corresponds to V4L2_CID_VFLIP.
Likewise, setting FIMC_REG_CITRGFMT_FLIP_Y_MIRROR bit causes Y-axis
image flip (horizontal flip) and thus it corresponds to V4L2_CID_HFLIP.
Currently the driver does X-axis flip when V4L2_CID_HFLIP is set and
Y-axis flip for V4L2_CID_VFLIP. Fix this incorrect assignment by setting
proper FIMC_REG_CITRGFMT register bits for ctx->hflip and ctx->vflip.

The V4L2_PIX_FMT_S5C_YUYV_JPG image formats consists of 2 planes, the
first containing interleaved JPEG/YUYV data and the second containing
meta data describing the interleaving method.
The image data is transferred with MIPI-CSI "User Defined Byte-Based
Data 1" type and is captured to memory by FIMC DMA engine.
The meta data is transferred using MIPI-CSI2 "Embedded 8-bit non Image
Data" and it is captured in the MIPI-CSI slave device and copied to
the bridge provided buffer.
To make sure the size of allocated buffers is correct for the subdevs
configuration when VIDIOC_STREAMON ioctl is invoked, an additional
check is added at the video pipeline validation function.
Flag FMT_FLAGS_COMPRESSED indicates the buffer size must be retrieved
from a sensor subdev.

This fixes potential invalid pointer de-reference, when
media_entity_cleanup() is called before video device
is unregistered.

The remaining drivers are mostly platform drivers. Name the
dir to reflect it.
It makes sense to latter break it into a few other dirs.
