arm64: dts: exynos: Add compatibles to sysreg nodes

System register nodes, implementing syscon binding, should use
appropriate compatible.  This fixes dtbs_check warnings:

  arch/arm64/boot/dts/exynos/exynos5433-tm2.dt.yaml: syscon@13b80000:
    compatible: ['syscon'] is not valid under any of the given schemas
