Subject: [PATCH v6 5/6] arm64: dts: ti: k3-am62: use opp_efuse_table for
 opp-table syscon

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 = <>;
