After rework of code by commit:

commit d95279685bb9690a6973226a3bd8a3bae65c2ad7
Author: Akshay Saraswat <akshay.s@samsung.com>
Date:   Wed Feb 4 16:00:03 2015 +0530

function get_mmc_clk() always returns -1 for Exynos 4.

This was caused by omitting, that SDHCI driver for Exynos 4,
calls get_mmc_clk(), with mmc device number as argument,
instead of pinmux peripheral id, like DW MMC driver for Exynos 5.

By this commit, the code directly calls a proper function
to get mmc clock for Exynos 4, without checking the peripheral id.
