ASoC: SOF: amd: fix for ipc flags check
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. 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.
