We thought it's fine to not model LDO supplies, as they may not always
follow PMIC.  But that might be even a good reason for modeling, so that
we can have a better DT description for the supplies.  I will change it
to:

	RPMH_VREG("ldo1",   LDO,  1,  &pmic5_nldo515,    "vdd-l1"),
	RPMH_VREG("ldo2",   LDO,  2,  &pmic5_nldo515,    "vdd-l2"),
	RPMH_VREG("ldo3",   LDO,  3,  &pmic5_pldo515_mv, "vdd-l3"),

Thanks for asking!
