Add another entry in the wkup_conf for the syscon node, and then use
that for the syscon in opp-table.

Marking entire wkup_conf as "syscon", "simple-mfd" is wrong and needs to
be addressed similar to how other child-nodes in wkup_conf are implemented
in the same file.

Also, rename syscon to bus and drop reg = <>;
