This patch initialises the local variable 'shift' to zero.
The uninitialised local variable 'shift' had garbage value and was
resulting in unwnated results in the functions exynos5_get_mmc_clk()
and exynos4_get_mmc_clk().

Changes since V1:
1)Updated the function exynos5_mmc_set_clk_div() to receive
'device_i'd as input parameter instead of 'index'.
Changes since V2:
1)Updation of commit message and resubmition of proper patch set.
Changes since V3:
1)Removed the new API exynos5_mmc_set_clk_div() from clock.c,
because existing API set_mmc_clk() can be used to set mmc clock.
Changes since V4:
1)Updated the subject line to reflect the changes present in this patch.
2)Changes of the file arch/arm/include/asm/arch-exynos/clk.h which
were present in this patch, have been moved out of this patch.
