mmc: fsl_esdhc: get clock directly from global data
This patch is to get clock directly from global data.
- Remove uclass clk api method. This was what i.MX platforms were
using, while QorIQ platforms weren't.
- Get clock only from global data, dropping mxc_get_clock().
QorIQ eSDHC controllers on one silicon use same reference clock.
