[PATCH 1/2] arm64: dts: ti: k3-am62: use opp_efuse_table for opp-table syscon

[Dhruva Gole <d-gole@ti.com>]

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.

This patch was sent previously here [1]. However there were some fixes
needed in the driver to make it work which have to go in as well. The
dependencies have been mentioned in the coverletter and a driver patch
that needs to go in after this patch is included as part of this series
itself.
