drm/rockchip: debugfs: Add extra enable option for vop dump feature

Browse Source 
Currently, the dump vop buffer feature is turned on and off through
`CONFIG_ROCKCHIP_DRM_DEBUG` marco. We want to control this at
runtime, so this patch adds a new option for enable to dump debugfs.

- DUMP_DISABLE: Disable dump and do not record plane info into list.
- DUMP_ENABLE: Record plane info into list.
- DUMP_KEEP: Record plane info into list and keep to dump plane.
