regulator: dt-bindings: qcom,rpmh: Correct PM8550 family supplies

PM8550 is different than PM8550VE/VS, because the latter has much
smaller amount of supplies (l1-3 and s1-6) and regulators.  The PM8550
has on the other hand one pin for vdd-l1-l4-l10 supplies.  Correct the
if:then: clause with their supplies.
