Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>: On Intel platforms the registers for DSP communications are used differently, the IPC dump information is not correct since important registers are not printed and existing ones are used a bit differently for IPC4. As a last step, enable the IPC timeout 'handling' and allow the printout of the now usefull IPC dump.
