Allow user to select between Nios2 R1 and R2. Since R1 and R2 are

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.

will eventually be converted to void.
See: commit 1f33c41c03da ("seq_file: Rename seq_overflow() to
seq_has_overflowed() and make public")
