The commit "i.mx: fsl_esdhc: add the i.mx6q support" (4692708d) introduces support for the i.MX6Q MMC host controller USDHC.
MXC_IPG_PERCLK sets the clock to 66MHz. This seems to be the default clock of the ESDHC IP found in < i.MX6 silicon. However, the default clock for the USDHC IP found in i.MX6 is 200MHz (MXC_ESDHC_CLK). This difference will cause a 3 times higher clock on SD_CLK than expected (see fsl_esdh.c -> set_sysctl()).
