Subject[PATCH 7/9] staging: fsl-mc: dpbp: drop unused APIs
Date
From: Laurentiu Tudor <laurentiu.tudor@nxp.com>

Leave only APIs that will be used in upcomming drivers.
The patch is mostly mechanical, with a couple exceptions:
- getters/setters were not removed even if only one of
them is being used
- versioning API was also left in place
They will be added back on an as-needed basis.

Signed-off-by: Laurentiu Tudor <laurentiu.tudor@nxp.com>
