arm64: dts: qcom: clean up 'regulator-allowed-modes' indentation

When recently adding the missing 'regulator-allowed-modes' properties it
appears that the binding example with its four-spaces indentation
(corresponding to a single tab, which is still to little) was copied
verbatim.

Drop the unnecessary first line break after 'regulator-allowed-modes'
properties and indent the single remaining continuation line properly.
