FW encapsulates information about section types (e.g DRAM, IRAM) inside module block header. This information can be used in order to correctly load the section to the appropriate place in memory. SOF Linux driver needs to know for each platform how to map the section type with the corresponding memory BAR. So, this patch introduces get_bar_index, a new operation inside snd_sof_dsp_ops. Intel platforms, usually load all the section in a contiguous memory area (usually denoted by sdev->mmio_bar) so things are relatively simple there. Anyhow, on i.MX8 IRAM and DRAM for example are mapped to distinct BARs. By default, if no get_bar function is provided the core implementation will always return sdev->mmio_bar so that there will be no need for a change to existing Intel code.
