[PATCH 2/3] arm64: dts: axis: Add samsung,exynos8895-uart compatible for serial node

Add the samsung,exynos8895-uart compatible in the serial node
and also add samsung,uart-fifosize property.

This is to remove the axis,artpec8-uart specific code (which is
kind of duplicated) from the driver and use the other matching
exynos8895 uart code for ARTPEC-8.
