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
---
changed with v1:
- add new patch 4 and 5.
- using cmd 'cat vdec' to show debug information instead of pr_info directly.
