Firmware will set dsp_ack to 1 when firmware sends response for the IPC command issued by host. Similarly dsp_msg flag will be updated to 1. During ACP D0 entry sequence, during firmware run sequence, Once the firmware sends the FW_READY message in the acp irq thread, dsp_ack_write register relative offset read from scratch memory points to garbage value. In this case, fw_state is SOF_FW_BOOT_READY_OK results in else condition execution printing below dmesg log. "IPC reply before FW_BOOT_COMPLETE". This is not an expected sequence. Fix the condition checks for ipc flags.

Firmware will set dsp_ack to 1 when firmware sends response for the IPC command issued by host. Similarly dsp_msg flag will be updated to 1. During ACP D0 entry, the value read from the sof_dsp_ack_write scratch flag can be uninitialized.

During ACP D0 entry, the value read from the sof_dsp_ack_write scratch flag can be uninitialized. A non-zero garbage value is treated as a pending DSP IPC ack before SOF_FW_BOOT_COMPLETE, causing a spurious "IPC reply before FW_BOOT_COMPLETE" log. Fix the condition checks for ipc flags.
