arm64: dts: qcom: sm8150-microsoft-surface-duo: fix typos in da7280 properties

The dlg,const-op-mode & dlg,periodic-op-mode were mis-names with twice
the "dlg," prefix, drop one to match the bindings.

This fixes:
sm8150-microsoft-surface-duo.dtb: da7280@4a: 'dlg,const-op-mode' is a required property
	from schema $id: http://devicetree.org/schemas/input/dlg,da7280.yaml#
m8150-microsoft-surface-duo.dtb: da7280@4a: 'dlg,periodic-op-mode' is a required property
	from schema $id: http://devicetree.org/schemas/input/dlg,da7280.yaml#
sm8150-microsoft-surface-duo.dtb: da7280@4a: 'dlg,dlg,const-op-mode', 'dlg,dlg,periodic-op-mode' do not match any of the regexes: 'pinctrl-[0-9]+'
	from schema $id: http://devicetree.org/schemas/input/dlg,da7280.yaml#

With the dlg,da7280.yaml converted from dlg,da7280.txt at [1].
