Subject: [PATCH V4 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.

**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@ti.com/
No changes, just combined it as part of Bryan's AM62A and AM62P series
and sending it all together.
