Enable SPL for i.MX8QXP MEK, and currently use SPL FIT. The SPL enable SPL_DM to use MMC/PINCTRL/POWER DOMAIN/CLK.
Note: SPL FIT could not support secure boot chain, because i.MX8/8X only support i.MX container format. This container format has not been upstreamed, so we use FIT for now. When SPL container supported, we could switch to that.
