This change addresses two warnings that are flagged by gcc relating to
potential access to the ssr and cks variables while they are uninitialised.

I have addressed this by initialising the values to
the defaults present in sci_baud_calc_hscif().

It is my analysis that cks is always initialised if used
but that without this change ssr may be accessed while uninitialised.

The code altered by this patch was introduced by commit
f303b364 ("serial: sh-sci: HSCIF support").

From Srinivas Kandagatla <srinivas.kandagatla@st.com>:

This patch-set adds basic support for STMicroelectronics STi series SOCs
which includes STiH415 and STiH416 with B2000 and B2020 board support.

STiH415 and STiH416 are dual-core ARM Cortex-A9 CPU, designed for
use in Set-top-boxes. The SOC support is available in mach-sti which
contains support code for STiH415, STiH416 SOCs including the generic
board support.

The reason for adding two SOCs at this patch set is to show that no new
C code is required for second SOC(STiH416) support.

  ARM: stih41x: Add B2020 board support
  ARM: stih41x: Add B2000 board support

This is the initial platform code for the TI-Nspire graphing
calculators. The platform support is rather unspectacular, but still
contains platform data for the LCD panel, which will get removed once
there is a DT binding for the AMBA CLCD driver.

In preparation of adding support for EXYNOS5420, which has many
peripherals similar to EXYNOS5250, a new common EXYNOS5 device tree
source file is created out of the exising EXYNOS5250 device tree
source file. Only the common nodes required for basic boot up on
EXYNOS5420 based boards are moved into this new file and the rest
of the common nodes would be moved subsequently.

EXYNOS5440 SoC is quite different from EXYNOS5250 and EXYNOS5420.
Hence it is not possible to reuse "exynos5.dtsi" for EXYNOS5440.
