i.MX8 only uses SOF_FW_BLK_TYPE_IRAM (1) and SOF_FW_BLK_TYPE_SRAM (3) bars, everything else is left as 0 in sdev->bar[] array.

If a broken or purposefully crafted firmware image is loaded with other types of FW_BLK_TYPE then a kernel crash can be triggered.

This is a fix which should have been at the start of the series.

The same is true for the next patch for imx8m, I'll move it ahead in the v2.
