Meet the following boot hang. " U-Boot SPL 2019.04-00661-gdc80a012e4 (Apr 25 2019 - 10:31:57 +0800) Trying to boot from MMC1

1. fdtdec_get_alias_seq will use "video" as base, however in alias node, we use ipux, so add new alias for U-Boot dts. 2. DM_VIDEO is enabled, however reserve_video is called before relocation, so to make DM_VIDEO work before relocation, need to set SYS_MALLOC_F_LEN 3. defconfig is updated with savedefconfig

Note: I do not have a video panel to test, but with this patch, U-Boot boots up again, below log.
