Commit 63589e92c2d9 ("clk: Ignore error and NULL pointers passed to
clk_{unprepare, disable}()") allows NULL or error pointer to be passed
unconditionally.
This patch is to simplify probe error and remove code paths.
However, we reserve the core clock checks in runtime suspend/resume code
because we want a little smaller latency.
This patch can be applied after the sdhci-pxav3 unbalanced pm/clock issues
patches being merged.
