Revert "arm: dts: rockchip: radxa-cm3-io, rock-3a: enable regulators for usb"

Remove regulator-boot-on prop from regulators now that the phy core has
support for phy-supply after the commit c57e0dcd9384 ("phy: add support
for phy-supply").

This reverts commit 7911f409ff20dce5995cc1b703a6e30c94022f6b.
