Please don't do that, don't change the meaning of already defined
clock identifiers. We should carefully assign the clock identifiers
based on the SoC documentation beforehand, not at will when we see
fit for development of the Linux driver. Please either add
DOUT_ACLK_CCORE_133 at the end of list or move this change to the
first patch in your series adding initial support for Exynos7 SoC.
