[PATCH 3/7] pinctrl: rockchip: use of_property_read_bool()

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

No Rockchip device tree actually sets a value for these properties and
neither kernel or barebox driver cares about the property value.

Thus replace of_property_read_u32 with of_property_read_bool for
simplification.
