ARM: dts: mx5: Split M53EVK into SoM and EVK parts
This patch splits the M53EVK device tree file into a common SoM part and an EVK part. This is needed to make it easier for users of the SoM to put it into different, non-reference baseboard. Signed-off-by: Marek Vasut <marex@denx.de> Signed-off-by: Shawn Guo <shawn.guo@freescale.com>
