arm: drop eSDHC clock getting in mxc_get_clock() for layerscape 

Although layerscape platforms reuse mxc_get_clock() of i.MX platforms,
eSDHC clock getting do not have to use it. It uses global data
gd->arch.sdhc_clk directly in fsl_esdhc driver. Even there are more
than one eSDHC controllers on SoC, they use same reference clock.
