nios2: use of_property_read_bool
Use of_property_read_bool instead of open-coding it as fpcu_has. Convert the members of struct cpuinfo from u32 to bool accordingly as they are only used as boolean anyhow. Signed-off-by: Tobias Klauser <tklauser@distanz.ch> Acked-by: Ley Foon Tan <lftan@altera.com>
