[media] v4l2-ioctl/exynos: fix G/S_SELECTION's type handling
The type field in struct v4l2_selection is supposed to never use the
_MPLANE variants. E.g. if the driver supports V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE,
then userspace should still pass V4L2_BUF_TYPE_VIDEO_CAPTURE.
The reasons for this are lost in the mists of time, but it is really
annoying. In addition, the exynos drivers didn't follow this rule and
instead expected the _MPLANE type.
To fix that code is added to the v4l2 core that maps the _MPLANE buffer
types to their regular equivalents before calling the driver.
Effectively this allows for userspace to use either _MPLANE or the regular
buffer type. This keeps backwards compatibility while making things easier
for userspace.
Since drivers now never see the _MPLANE buffer types the exynos drivers
had to be adapted as well.
