clk: samsung: avoid warning message on legacy Exynos (auto clock gating)

We currently print a warning message that the IO memory size is not
compatible with automatic clock gating for many Exynos-based boards,
including legacy ones, even if not requested to enable automatic clock
gating in the first place.

Change the test in question to avoid that warning.
