In oder to get each instance information according to test command, adding
one file node "vdec".
Can use echo command to set different string value as 'echo -picinfo > vdec'
to get real and aligned resolution.

If you want to use debugfs (which is a good choice!), you should use debugfs!
This means that you shouldn't print this kind of information to the kernel,
but rather to a debugfs entry.
Example:
$ echo "-picinfo" > vdec
$ cat vdec
resolution: real(1024x768)=>align(something)
This is the same for all of the commits of this series, so, please properly
use debugfs.
