[media] v4l: Remove "_ACTUAL" from subdev selection API target definition names

Browse Source 
The string "_ACTUAL" does not say anything more about the target names. Drop
it. V4L2 selection API was changed by "V4L: Remove "_ACTIVE" from the
selection target name definitions" by Sylwester Nawrocki. This patch does
the same for the V4L2 subdev API.

<para>BOUNDS targets is the smallest rectangle that contains
all valid ACTUAL rectangles. It may not be possible to set the
ACTUAL rectangle as large as the BOUNDS rectangle, however.
This may be because e.g. a sensor's pixel array is not
rectangular but cross-shaped or round. The maximum size may
also be smaller than the BOUNDS rectangle.</para>
