Hmm, maybe we beed to have 2 values for it then:
CONFIG_SYS_NAND_SPL_U_BOOT_OFFS
CONFIG_SYS_NAND_TPL_U_BOOT_OFFS

And select which one to use depending we are building the SPL or the TPL,
then both could go to Kconfig

See above, if we do something like that, then at one point in time we
can choose to put in some effort to convert the remaining boards,
and just drop the depends.
