With the added exception handling support if the firmware fails to boot up we are trying to do a panic dump from the telemetry slot. The slot offsets would have been configured only after receiving the FW_READY message which makes this panic dump unusable for early boot failures.

With IPC4 the DSP window offsets are at standard places unlike IPC3 where the offsets needs to be queried from the FW_READY message.

Move the offset configuration to sof_ipc4_init from the fw_ready handler.
