arm64: dts: mt8173: Fix auxadc node

commit a3207d644fb89e5d7d5e01f00c04dcfc6d2d44d5 upstream.

The devicetree node for mt8173-auxadc lacks the clock and
io-channel-cells property. This leads to a non-working driver.

	mt6577-auxadc 11001000.auxadc: failed to get auxadc clock
	mt6577-auxadc: probe of 11001000.auxadc failed with error -2

Fix these fields to get the device up and running.

nodes")
