i.MX8MP SDHC use CLK_IMX8MP_DUMMY clk entry. Without the clk, the bulk api will return failure.
The correct entry should be replaced with IMX8MP_IPG_ROOT clk in device tree. This will be done in Kernel device tree and sync to U-Boot in future: https://lore.kernel.org/all/20241012025221.1728438-1-peng.fan@oss.nxp.com/
