Move lvs1 and lvs2 regulator nodes up in the rpmh-regulators
list to workaround a boot regression uncovered by the upstream
commit ad44ac082fdf ("regulator: qcom-rpmh: Revert "regulator:
qcom-rpmh: Use PROBE_FORCE_SYNCHRONOUS"").
Without this fix DB845c fail to boot at times because one of the
lvs1 or lvs2 regulators fail to turn ON in time.
