[PATCH 1/1] imx: rom api: fix image offset computation

According to the table 6-25 "Primary image offset and IVT offset details", in the IMX8MNRM, the ROM expects the following image offset:
SD: 32KB eMMC: 0 if image is in boot partion and 32KB if it is on user partition NAND: 0 FlexSPI: 4KB SPI: 0
On eMMC, it is more likely that U-Boot is on the boot partion, so rework the offset computation by handling the two specific cases (SD and FlexSPI).

Likely, but not really. I have a product where it's on the eMMC but not in a boot partition. If this gets committed, should I sent a diff to revert it? :-) I'm not (yet?) using that code, but shouldn't there be a way to see if we are on a boot partition or not?
Best regards, Patrick
