ARM: EXYNOS: Create virtual I/O mapping for Chip-ID controller using device tree

On device tree enabled exynos platforms, retrieve the physical base address
of the chip-id controller from device tree and create a virtual I/O mapping
for the chip-id controller. This helps to remove the chip-id controller entry
from the statically defined I/O mapping tables.
