Environment is the hard one to move out from config.h and in to, well, I
don't know what.  I think there's also a handful of symbols like
CONFIG_SPL_MAX_SIZE that are a little tricky to convert directly (they
do math based on other symbols) rather than just as evaluate-and-set.
Right now, a little more than half of the unmigrated symbols are
CONFIG_SYS_xxx things and those likely should become SYS_xxx things.  Of
the ones that don't just go away.
