ARM: exynos: Remove static mapping of SCU SFR
Lets remove static mapping of SCU SFR mainly used in CORTEX-A9 SoC based
boards. Instead use mapping from device tree node of SCU.

[mszyprow: rebased, added fallback to scu_a9_get_base() when no SCU DT
node is available, removed compatibility break warning, fixed non-SMP
build, keep SCU base mapping to avoid issues with calls from CPUidle]
