ASoC: SDCA: bug fix while parsing mipi-sdca-control-cn-list

Browse Source 
"struct sdca_control" declares "values" field as integer array.
But the memory allocated to it is of char array. This causes
crash for sdca_parse_function API. This patch addresses the
issue by allocating correct data size.
