For silicon revision A1, the USB instance number for USB1 is 3 and for
USB2 it is 4. This changed for revision B0 where the USB instance number
for USB1 is 0 and for USB2 it is 1, which is the intended instance
number. Select the correct numbering according to the selected revision
in the defconfig. The config for the B0 revision is IMX95 and for A1 it
is IMX95_A0.
This patch is based on the information provided by:
"AN14750 Migration Guide from i.MX 95 A1 to B0; Rev. 1.0" .

It seems this can also be made even more generic:
-if (IS_ENABLED(CONFIG_IMX95))
+if (is_imx95() && (soc_rev() < CHIP_REV_2_0))
