control: Remove access to the deprecated dimen fields

The dimen fields of control element has been deprecated, and it's
finally dropped in kernel 5.6 ABI definition.  Remove the
corresponding accesses in alsa-lib code.

As of this patch, it's disabled via ifdef, just to be sure.  The
disabled code should be removed in a later stage as a cleanup.
