The recent introduction of the ACP/PSP communication for IRAM/DRAM fence
register modification breaks the audio support on Valve's Steam Deck
OLED device.

It causes IPC timeout errors when trying to load DSP topology during
probing:

It's worth noting this is the only Vangogh compatible device for which
signed firmware support has been enabled in AMD ACP SOF driver via
acp_sof_quirk_table.

Hence, use this information and skip IRAM/DRAM size modification for Vangogh
platforms having the signed_fw_image field set.

Programming ACP_IRAM_DRAM_FENCE register to modify the size of IRAM and 
DRAM and it's noting related to signed or unsigned fw_image.

This ACP_IRAM_DRAM_FENCE register writing need to do before starting sha 
dma.

Unfortunately it doesn't fix the issue - I tested with the psp_send_cmd()
calls moved to various positions before the line

  snd_sof_dsp_write(sdev, ACP_DSP_BAR, ACP_SHA_DMA_CMD, ACP_SHA_RUN);

and I keep getting the IPC timeouts.

However, if I simply comment out the second psp_send_cmd() line

  psp_send_cmd(adata, MBOX_ACP_IRAM_DRAM_FENCE_COMMAND | MBOX_ISREADY_FLAG);

the problem is solved, even when the first psp_send_cmd() is kept in the
original position.

Anything else worth trying?

Otherwise I would rework the patch to add a dedicated quirk for getting
this ACP_IRAM_DRAM_FENCE processing skipped for Steam Deck OLED.

Thanks,
Cristian
