MLK-20660 imx8: Check the ROM pass over info only for RevA 

Only the ROM on RevA will pass over some info into OCRAM. U-boot gets
the info to determine whether it is eMMC fastboot.
Thus, change that codes only for RevA, otherwise if we protect
the OCRAM used by SPL on RevB, u-boot will fail to access it.
