Add the vdd-*-supply properties to the rpmh-regulators nodes, so that
the parent regulators can be enabled when needed.
PM7325's l3 and l5 are supplied by vreg_s2b ("ebi.lvl"), however since
that regulator is not modelled as regulator, skip the -supply
properties for those two LDOs.
And document what the "missing" regulators are used for.
