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.

**DEPENDS ON:** PATCH 6/6: cpufreq: ti-cpufreq: Update the efuse/rev offsets
Link to v1: https://lore.kernel.org/all/20240902093222.2828345-2-d-gole@xxxxxx/
No changes, just combined it as part of Bryan's AM62A and AM62P series
and sending it all together.

This can be done in a separate patch after this one. You'll also
want to change the syscon@43000000 to bus@43000000, and drop the
"reg = <>;" line at the same time.
