ARM: dts: qcom: ipq4019: drop 'regulator' property from SAW2 devices

The SAW2 device should describe the regulator constraints rather than
just declaring that it has the regulator.

Drop the 'regulator' property. If/when CPU voltage scaling is
implemented for this platform, proper regulator nodes show be added
instead.
