A few boards have shown to be required to properly configure pinctrl for the fixed regulator gpio pin used by sdmmc before being able to read from SD-cards. Include the related gpio, regulator and pinctrl nodes and enable related Kconfig options so that pinctrl can be configured in SPL for boards that may be affected by such issue. Also change to imply SPL_DM_SEQ_ALIAS for all boards because it must be enabled for working gpio usage in SPL after a future DT sync.
