mx35: Fix eSDHC clocks

Browse Source 
Each eSDHC instance has a dedicated clock.

gd->sdhc_clk must also be set accordingly. This is good for the case only a
single SDHC instance is used (initialization made with fsl_esdhc_mmc_init()). A
future patch will fix the multi-instance use case (initialization made directly
with fsl_esdhc_initialize()).
