target/nios2: Move nios2_check_interrupts() into target/nios2

Browse Source 
The function nios2_check_interrupts)() looks only at CPU-internal
state; it belongs in target/nios2, not hw/nios2.  Move it into the
same file as its only caller, so it can just be local to that file.

This removes the only remaining code from cpu_pic.c, so we can delete
that file entirely.
