bsp/motorola_powerpc: Remove obsolete GCC option
commit 20c89ab7c5091ee48535392cae2177aa1a1c43eb
Author: Segher Boessenkool <segher@kernel.crashing.org>

rs6000: Remove -mstring
-mstring is only enabled by default on 601, and with -Os on some
configurations. It is almost always slower (than not using it) and
does not very often lead to smaller code.
This patch disables it. If a user uses -mstring he gets a warning
(but not with -mno-string). I left the target attribute in place, it
just doesn't do anything anymore.
The patch also deletes a whole bunch of code. The 'N' and 'O' output
modifiers are now unused, but now is not the time to delete them.
