media: smiapp: Don't get binning limits dynamically
The driver implementation assumed the binning limits could change
dynamically based on the binning configuration. This is not actually the
case; these limits are static and suitable to be used with all binning
configurations but possibly not optimal limit for many of those
configurations.
