  Need to change kernel driver to open decode and encode debug log at current period,
it's very unreasonable. Adding debugfs common interface to support decode and encode,
using echo command to control debug log level and getting useful information for each
instance.

patch 1 add dbgfs common interface.
patch 2~5 support decode.
patch 6~7 support encode
patch 8 add help function
---
changed with v3:
- add help function for patch 8
- remove append '\0' and enlarge buffer size for patch 4
changed with v2:
- using pr_debug and dev_dbg instead of pr_info for patch 2.
- fix word fail: informatiaoin -> information for patch 3.
- used to print each instance format information for patch 5.
changed with v1:
- add new patch 4 and 5.
- using cmd 'cat vdec' to show debug information instead of pr_info directly.
