topology: pre-processor: Move the call to expand variables Remove the call to snd_config_expand_custom() to expand the top-level input config. And replace it with calls to snd_config_evaluate_string() for each non-compound config while processing individual objects. This will allow retreving variable definitions from object attribute values and global definitions. Add a new field "current_obj_cfg" to hold the current object config being pre-processed. This will facilitate adding simple math expressions for computing attribute values for objects based on other attributes. For ex: we can set the expression for buffer size as follows: buffer_size "$[($in_channels * 48) * 4]" The buffer_size attribute value will be computed with the attribute value "in_channels" based on the expression above. So if $in_channels = 2, buffer_size will be evaluated to 384. Additionally this change also permits computing attribute values based on previously computed values. For example: buffer_size "$[($in_channels * 48) * 4]" dma_buffer_size "$[$buffer_size * 2]" dma_buffer_size will be computed as 768. Note that the order of definitions for buffer_size and dma_buffer_size matters because the evaluation for dma_buffer_size depends on the evaluation of buffer_size. In order to conform to this, the tplg_object_copy_and_add_param() is modified to add attribute configs from class config to an object using snd_config_before() instead of snd_config_add(). With this change, we no longer need to set the auto_attr_updater for buffer type widget objects. So remove it.
