[PATCH] ARM: stm32mp: skip ft_system_setup when the soc node is absent

[Patrick Delaunay]

The function ft_system_setup should don't return an error when the
/soc node is absent in the provided device tree but just skip the
updates.

This patch solves an issue when the U-Boot pytest is executed on board.
