Exynos5800 is a derivative of Exynos5420 with higher
clock speeds and most other IP blocks remaining the same
except for a few.
Due to the similarities with 5420, following is done to
achieve maximum code re-use:
- Use the same 5420 clock file with few changes for adding
extra 5800 clocks.
-
Exynos5800 is an octa core SoC which is based on the 5420
platform. This patch adds the basic SoC support.

Exynos5800 clock structure is mostly similar to 5420 with only
a small delta changes. So the 5420 clock file is re-used for
5800 also. The common clocks for both are seggreagated and few
clocks which are different for both are separately initialized.
Most of the nodes of exynos5420 remains same for exynos5800.
So moving the common dt nodes to exynos5-octa.dtsi.
The pinctrl dtsi is completely re-used and is renamed to
exynos5-octa-pinctrl.dtsi.

The offset of register DSIM_PLLTMR_REG in Exynos5420 is different
from the one in Exynos4 SoC.
In case of Exynos5420 SoC, there is no frequency band bit in DSIM_PLLCTRL_REG,
and it uses DSIM_PHYCTRL_REG and DSIM_PHYTIMING*_REG instead.
So this patch adds driver data to distinguish it.

The two functions to write out to the console (one used in normal
console mode and one in polling console mode) were slightly different.
One used a barrier() in its loop and the other a cpu_relax(). The

read the port anyway.
The s3c24xx_serial_console_putchar() is _only_ ever used by
