R29 was an unlucky choice as with recent toolchains (gcc-4.2.x) gcc
will refuse to use load/store multiple insns; instead, it issues a
list of simple load/store instructions upon function entry and exit,
resulting in bigger code size, which in turn makes the build for a
few boards fail.
Use r2 instead.

With recent toolchain versions, some boards would not build because
or errors like this one (here for ocotea board when building with
ELDK 4.2 beta):
ppc_4xx-ld: section .bootpg [fffff000 -> fffff23b] overlaps section .bss [fffee900 -> fffff8ab]
For many boards, the .bss section is big enough that it wraps around
at the end of the address space (0xFFFFFFFF), so the problem will not
be visible unless you use a 64 bit tool chain for development. On
some boards however, changes to the code size (due to different
optimizations) we bail out with section overlaps like above.
The fix is to add the NOLOAD attribute to the .bss and .sbss
sections, telling the linker that .bss does not consume any space in
the image.

Update the cpu_init_f() function in cpu/mpc83xx/cpu_init.c to program the
bitfields for all 83xx processors. The code to update some bitfields was
compiled only on some processors. Now, the bitfields are programmed as long
as the corresponding CFG_SCCR option is defined in the board header file.
This means that the board header file should not define any CFG_SCCR macros
for bitfields that don't exist on that processor, otherwise the SCCR will be
programmed incorrectly.
