msm: vidc: Add support for querying controls
Add support in driver to query for control information.
This helps clients to findout limits for various controls
and sets the values accordingly.
Also update the control limits based on Venus HW capabilities.
This helps to prevent rogue clients not to set invalid values
to HW.
