imx8ulp: Add workaround for eMMC boot

Browse Source 
When booting from boot part1/2, the image offset should be 0, but
ROM has a bug to return 0x8000. Has to workaround the issue before
ROM fix it.

Use a ROM function to know boot from emmc boot part or user part
So we can set the image offset accordingly.
