Commit 4d11c62ca8d7 ("clkdev: report over-sized strings when creating
clkdev entries") revealed that clock lookup is registered for all fixed
clocks. The mentioned commit added a check if the registered name is not
too long. This fails for some clocks registered for Exynos542x SoCs family.
This lookup is a left-over from early common clock framework days, not
really needed nowadays, so remove it to avoid further issues.
This commit causes a warning to appear during startup on Exynos 4x12:
> [ 0.000000] exynos4_clk_register_finpll: failed to lookup parent clock xusbxti, assuming fin_pll clock frequency is 24MHz

The warning seems to come from exynos4_clk_register_finpll in
drivers/clk/samsung/clk-exynos4.c, where clk_get fails with error code -2.
