[PATCH 7/7] ASoC: SOF: Intel: mtl: Correct the mtl_dsp_dump output

[Peter Ujfalusi <peter.ujfalusi@xxxxxxxxxxxxxxx>]

The ROM/firmware state handling has changed between CAVS and ACE
architecture:
CAVS: ROM and firmware uses the SRAM window for the state and status/error
code reporting

ACE: ROM code is using two registers to report the state and error while
the firmware is using the SRAM window to report states and status/error
codes.

Use the generic hda_dsp_get_state() to decode ROM state and error codes and
print out the firmware state and status/error code only if the SRAM
window is accessible - the firmware is booted and the Status readout is
not 0xffffffff.
