VA drivers allocate surfaces given their properties, so there's no need to provide a buffer size to the VA pool. Though, the buffer size is provided by the driver, or the canonical size is used for single planed surfaces. This patch removes the need to provide a size for the function gst_va_pool_new_with_config() and adds a helper method to retrieve the surface size, gst_va_pool_get_buffer_size(). Also change the callers accordingly. Changes for custom VA pool creation will be addressed in the following commits.
