commit 82eb56b102aa2294961bb65a244b537d521b9d12

libpayload: minor cleanups
Apply some const correctness to const/non-const strings in libc and
libpci (what an ugly cast that was).
Remove duplicated NULL test in printf_putstr(), already done in
print_string() - reduces size of libpayload by a few bytes.
