[PATCH 4/6] ASoC: SOF: Intel: mtl: Print relevant register in ipc_dump

The use of the IPC registers are different between IPC3 and IPC4.
The ipc_dump needs to use different prints depending on the used IPC
protocol.

The existing code was printing registers relevant for IPC3, which is not
even supported on MTL.
