spi: add bits_per_word to proxy structure ...

During the creation of a new spi device, we need to
have the possiblility to give the bits_per_word value
to master->setup.

As a matter of fact, spi master could check the spi
device bits_per_word and compare this value against its
capabilities.

include/linux/stat.h: make struct stat unified ...

The current version of struct stat has been taken from an
ancient Linux Kernel. It looks different on different architectures
to support different userspace formats of struct stat. As we do
not have a userspace on barebox there is no need to keep different
versions.

Also, this unification make MIPS arch possible.

Revert "fix printf warnings" ...

While getting rid of all the format(barebox_printf) warnings was nice,
it caused the printf calls in arch/sandbox/os/common.c to get directed
to the barebox versions rather than the libc ones causing a crash:

E.G. before this revert:
nm -a barebox|grep -w printf
0000000000404fa3 T print

And after:
nm -a barebox|grep -w printf
U printf@@GLIBC_2.2.5

fix printf warnings ...

With sandbox printf is redefined as barebox_printf so that it does
