It seems we should handle this similarly to
arch/arm/mach-imx/imx8m/soc.c, where peripherals are disabled
according to the SoC fuses.

Since this is a property of the SoC rather than a particular board, I
would prefer to implement the fuse-based fixup once in the common
i.MX95 SoC code instead of adding the same board_fix_fdt()
implementation to every i.MX95 board.

This would also avoid requiring each new i.MX95 board to duplicate
this code in the future.

Could you please move this to the common i. MX95 SoC code? If there is
a technical reason we can't do that, we can revisit the per-board
approach.

Thanks,

Fabio Estevam
