drivers: use DT_INST_PROP over DT_INST_PROP_OR if possible

It might happens that DT(_INST)_PROP_OR is used with boolean properties.
For instance:

	.single_wire = DT_INST_PROP_OR(index, single_wire, false),	\
	.tx_rx_swap = DT_INST_PROP_OR(index, tx_rx_swap, false),	\

This is not required as boolean properties are generated with false
value when not present, so the _OR macro extension is superflous
and the above code can be replaced by:

	.single_wire = DT_INST_PROP(index, single_wire),		\
	.tx_rx_swap = DT_INST_PROP(index, tx_rx_swap),			\
