ARM: dts: stm32: split sdram pin & timing parameter into specific board dts
As different boards has their own sdram hw connection, mount different sdram modules, so move sdram timing parameter and pin configuration to their board device tree. Signed-off-by: dillon min <dillon.minfei@gmail.com> Reviewed-by: Patrice Chotard <patrice.chotard@foss.st.com>
