Switch the Phanbell i.MX8MQ SPL to full Driver Model (DM) boot flow by moving early device initialization into devicetree and enabling the required SPL DM subsystems. Mark GPIO, USDHC, pinctrl, and regulator nodes with bootph-pre-ram so they are available during SPL. With DM handling MMC and power rails, remove legacy board-specific USDHC, GPIO, and pad setup code from SPL. Update the SPL initialization sequence to use spl_early_init(), clears BSS earlier, and explicitly enables USDHC clocks before handing off to board_init_r(). Signed-off-by: Peng Fan <peng.fan@nxp.com>
