f32xbase/f32x/c2-ben.c
Werner Almesberger e614d15fef Cleaned up command-line parsing. Added option -n to disable target power.
- f32x/c2-ben.c: removed #include <stdio.h> left over from debugging
- f32x/f32x.c (main): command-line parsing now uses getopt() and is done
  before trying to talk to the target
- f32x/c2-drv.h (c2_ops), f32x/c2.h (c2_init), f32x/c2.c (c2_init),
  f32x/c2-om.c (om_init): pass "power" argument along the init call chain
- f32x/c2-ben.c (ben_init): added target power switching
- f32x/f32x.c (usage, main): new option -n to disable target power
