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.

Add cpufreq controller device node for Exynos5440 SoC for passing
parameters like controller base address, interrupt and cpufreq
table. This node is added outside cpu0 as this driver is now a platform
driver and a new device structure is needed.

This patch adds device tree node for the SYSREG registers block
found in Samsung S5P/Exynos SoC series. The SYSREG module
generates control signals for the ARM CPU and various IP blocks
and buses. SYSREG block registers are exposed through APB bus
interface. A sysreg device tree node is to be associated with
mfd syscon driver and all SYSREG clients should use regmap
interface it provides. It allows to eliminate any possible races
and conflicts should different drivers attempt to concurrently
access same register.

In legacy setup, sclk_mmc{0,1,2,3} used PRE_RATIO bit-field (8-bit wide)
instead of RATIO bit-field (4-bit wide) for dividing clock rate.

With current common clock setup, we are using RATIO bit-field which
is creating FIFO read errors while accessing eMMC. Changing over to
use PRE_RATIO bit-field fixes this issue.
