ARM: stm32: Perform node compatible check for KS8851 early
Check the compatible string of ethernet1 node for KS8851 very early on, before calling uclass_get_device_by_of_path() which might initialize the device and possibly attempt to configure MAC address into device which is not KS8851. Doing the compatibility check early prevent this. Signed-off-by: Marek Vasut <marek.vasut@mailbox.org> Reviewed-by: Patrice Chotard <patrice.chotard@foss.st.com>
