ARM: EXYNOS: Avoid early use of of_machine_is_compatible()
The recent commit "ARM: EXYNOS: add support for EXYNOS5440 SoC" broke
support for exynos5250 because of_machine_is_compatible() was used too
early in the boot process. It also probably meant that the exynos5440
failed to use the proper iotable. Switch to use
of_flat_dt_is_compatible() in both of these cases.
The failure I was seeing in exynos5250 because of this was:
Division by zero in kernel.
