    The QorIQ eSDHC controller supports two reference clocks. They are
    platform clock and periperhal clock. The global variable sdhc_clk
    has already been used for platform clock.
    This patch is to add another global variable sdhc_per_clk for
    periperhal clock, which provides higher frequency and is required
    to be used for SD UHS and eMMC HS200/HS400 speed modes.
