ASoC: SOF: ops: add new 'is_chain_dma_supported' callback
IPC4 introduced a 'chain-dma' mode when host and link DMA are
connected by firmware without using a regular pipeline or the ability
to add intermediate connections. This mode is not available on all
platforms and all links, so add a platform-specific callback to help
the SOF ipc4-topology core handle different hardware+firmware
configurations.
