In case of a secondary image boot from the user area of an eMMC device,
the correct offset must be calculated. The offset is fused in the fuse
IMG_CNTN_SET1_OFFSET of the i.MX8M Nano and Plus. The calculation of the
offset is described in the reference manual (IMX8MNRM Rev. 2, 07/2022
and IMX8MPRM Rev. 1, 06/2021):
The fuse IMG_CNTN_SET1_OFFSET (0x490[22:19]) is defined as follows:
* Secondary boot is disabled if fuse value is bigger than 10,
n = fuse value bigger than 10.
* n == 0: Offset = 4MB
* n == 2: Offset = 1MB
* Others & n <= 10 : Offset = 1MB*2^n

Factor out parsing of ROM log in function spl_mmc_emmc_boot_partition().
This can be helpful to detect a secondary image boot without fiddling
around with MMC partitions. This way for example, U-Boot is able to
detect a secondary image boot and can enter some fallback scenario like
starting a recovery mode.

It doesn't seem appropriate for arch/SOC to use a board-level
functionality (CONFIG_OF_BOARD_FIXUP), because this prevents boards
that need to do FDT fixup from using that feature.
Also, this code is completely dead and useless (from comments by
Rasmus Villemoes on the mailing list):
- No in-tree imx8m-based board seems to set CONFIG_OF_BOARD_FIXUP
- The nodes which that function wants to disable don't even exist in
the U-Boot copy of imx8mp.dtsi.
This code was introduced in commit 35bb60787b. It seems to be some
random import of code from downstream NXP U-Boot, with a commit
