bloblist: Rework bloblist_init and bloblist_maybe_init

With bloblist, we need to both see if one already exists as well as
create one if it does not. However, the current implementation leads to
odd cases where we attempt to create a bloblist before this is possible
and have things be overly complicated when we are given one to work
with.

This reworks things to instead have a bloblist_exists function, which as
the name implies checks for an existing bloblist. This is used in
the case of booting, to see if we have one and in turn if we have a
device tree there as well as in the bloblist_init function to see if we
need to do anything.

In practical details, we move the logic from bloblist_init that was
checking for a bloblist to the new bloblist_exists function and then can
clarify the logic as it is much easier to state when we know we do not
have one rather than all the ways we might have one. Then we have the
locations that set gd->bloblist now also set the GD_FLG_BLOBLIST_READY
flag.
